Harry Potter


Harry Potter is a series of seven fantasy novels written by the British author J. K. Rowling. The series, named after the titular character, chronicle the adventures of a wizard, Harry Potter, and his friends Ronald Weasley and Hermione Granger, all of whom are students at Hogwarts School of Witchcraft and Wizardry. The main story arc concerns Harry's quest to overcome the Dark wizard Lord Voldemort, who aims to become immortal, conquer the wizarding world, subjugate non-magical people, and destroy all those who stand in his way, especially Harry Potter.
Since the release of the first novel, Harry Potter and the Philosopher's Stone, on 30 June 1997, the books have gained immense popularity, critical acclaim and commercial success worldwide.[2] The series has also had some share of criticism, including concern for the increasingly dark tone. As of June 2011, the book series has sold about 450 million copies, making it the best-selling book series in history, and has been translated into 67 languages.[3][4] The last four books consecutively set records as the fastest-selling books in history.
A series of many genres, including fantasy, coming of age, and the British school story (with elements of mystery, thriller, adventure, and romance), it has many cultural meanings and references.[5] According to Rowling, the main theme is death.[6] There are also many other themes in the series, such as prejudice and corruption.[7]
The series was originally printed in English by two major
publishers, Bloomsbury in the United Kingdom and Scholastic Press in the United States. The books have since been published by many publishers worldwide. The books, with the seventh book split into two parts, have been made into an eight-part film series by Warner Bros. Pictures, the highest-grossing film series of all time. The series also originated much tie-in merchandise, making the Harry Potter brand worth in excess of $15 billion.[8] Thanks to the success of the books and films, Harry Potter has also been used for a theme park, The Wizarding World of Harry Potter in Universal Parks & Resorts' Islands of Adventure.

Further information: Harry Potter universe
The novels revolve around Harry Potter, an orphan who discovers at the age of eleven that he is a wizard, living within the ordinary world of non-magical people, known as Muggles.[9] His ability is inborn and such children are invited to attend a school that teaches the necessary skills to succeed in the wizarding world.[10] Harry becomes a student at Hogwarts School of Witchcraft and Wizardry and it is here where most of the novels' events take place. As Harry develops through his adolescence, he learns to overcome the problems that face him: magical, social and emotional, including ordinary teenage challenges such as friendships and exams, and the greater test of preparing himself for the
confrontation that lies ahead.[11]
Each book chronicles one year in Harry's life[12] with the main narrative being set in the years 1991–98.[13] The books also contain many flashbacks, which are frequently experienced by Harry viewing the memories of other characters in a device called a Pensieve.
The environment Rowling created is completely separate from reality yet also intimately connected to it. While the fantasy land of Narnia is an alternative universe and the Lord of the Rings' Middle-earth a mythic past, the wizarding world of Harry Potter exists in parallel within the real world and contains magical versions of the ordinary elements of everyday life. Many of its institutions and locations are recognisable, such as London.[14] It comprises a fragmented collection of overlooked hidden streets, ancient pubs, lonely country manors and secluded castles that remain invisible to the Muggle population.[10]
Early years
When the first novel of the series Harry Potter and the Philosopher's Stone (published in some countries as Harry Potter and the Sorcerer's Stone) opens, it is clear some remarkable event has taken place in the wizarding world, an event so very remarkable, even the Muggles notice signs of it. The full background to this event and to the person of Harry Potter is only revealed gradually, through the series. After the introductory chapter, the book leaps forward to a time shortly before Harry Potter's eleventh birthday, and it is at this point that his background begins to be revealed.
Harry's first contact with the wizarding world is through a half-giant, Rubeus Hagrid, keeper of grounds and keys at Hogwarts. Hagrid reveals some of Harry's history.[15] Harry learns that as a baby he witnessed his parents' murder by the power-obsessed dark wizard, Lord Voldemort, who then attempted to kill him also.[15] For reasons not immediately revealed, the spell with which Voldemort tried to kill Harry rebounded. Harry survived with only a lightning-shaped scar on his forehead as a memento of the attack, and Voldemort disappeared. As its inadvertent saviour from Voldemort's reign of terror, Harry has become a living legend in the wizarding world. However, at the orders of the venerable and well-known wizard Albus Dumbledore, the orphaned Harry had been placed in the home of his unpleasant Muggle (non-wizard) relatives, the Dursleys, who had him safe but hid his true heritage from him in hopes that he would grow up "normal".[15]
With Hagrid's help, Harry prepares for and undertakes his first year of study at Hogwarts. As Harry begins to explore the magical world, the reader is introduced to many of the primary locations used throughout the series. Harry meets most of the main characters and gains his two closest friends: Ron Weasley, a fun-loving member of an ancient, large, happy, but hard-up wizarding family, and Hermione Granger, a gifted and hardworking witch of non-magical parentage.[15][16] Harry also encounters the school's potions master, Severus Snape, who displays a deep and abiding dislike for him. The plot concludes with Harry's second confrontation with Lord Voldemort, who in his quest for immortality, yearns to gain the power of the Philosopher's Stone, a substance that gives everlasting life.[15]
The series continues with Harry Potter and the Chamber of Secrets describing Harry's second year at Hogwarts. He and his friends investigate a 50-year-old mystery that appears tied to recent sinister events at the school. Ron's younger sister, Ginny Weasley, enrols in her first year at Hogwarts, and finds a notebook which turns out to be Voldemort's diary from his school days. Ginny becomes possessed by Voldemort through the diary and opens the "Chamber of Secrets", unleashing an ancient monster which begins attacking students at Hogwarts. The novel delves into the history of Hogwarts and a legend revolving around the Chamber. For the first time, Harry realises that racial prejudice exists in the wizarding world, and he learns that Voldemort's reign of terror was often directed at wizards who were descended from Muggles. Harry also learns that his ability to speak Parseltongue, the language of snakes, is rare and often associated with the Dark Arts. The novel ends after Harry saves Ginny's life by destroying a basilisk and the enchanted diary which has been the source of the problems.
The third novel, Harry Potter and the Prisoner of Azkaban, follows Harry in his third year of magical education. It is the only book in the series which does not feature Voldemort. Instead, Harry must deal with the knowledge that he has been targeted by Sirius Black, an escaped murderer believed to have assisted in the deaths of Harry's parents. As Harry struggles with his reaction to the dementors—dark creatures with the power to devour a human soul—which are ostensibly protecting the school, he reaches out to Remus Lupin, a Defence Against the Dark Arts teacher who is eventually revealed to be a werewolf. Lupin teaches Harry defensive measures which are well above the level of magic generally shown by people his age. Harry learns that both Lupin and Black were close friends of his father and that Black was framed by their fourth friend, Peter Pettigrew.[17] In this book, another recurring theme throughout the series is emphasised—in every book there is a new Defence Against the Dark Arts teacher, none of whom lasts more than one school year.

During Harry's fourth year of school (detailed in Harry Potter and the Goblet of Fire) Harry is unwillingly entered as a participant in the Triwizard Tournament, a dangerous contest where Harry must compete against a witch and a wizard "champion" from visiting schools as well as another Hogwarts student.[18] Harry is guided through the tournament by Professor Alastor "Mad-Eye" Moody, who turns out to be an impostor – one of Voldemort's supporters named Barty Crouch, Jr in disguise. The point at which the mystery is unravelled marks the series' shift from foreboding and uncertainty into open conflict. Voldemort's plan to have Crouch use the tournament to bring Harry to Voldemort succeeds. Although Harry manages to escape, Cedric Diggory, the other Hogwarts champion in the tournament, is killed and Voldemort re-enters the wizarding world with a physical body.
In the fifth book, Harry Potter and the Order of the Phoenix, Harry must confront the newly resurfaced Voldemort. In response to Voldemort's reappearance, Dumbledore re-activates the Order of the Phoenix, a secret society which works from Sirius Black's dark family home to defeat Voldemort's minions and protect Voldemort's targets, especially Harry. Despite Harry's description of Voldemort's recent activities, the Ministry of Magic and many others in the magical world refuse to believe that Voldemort has returned.[19] In an attempt to counter and eventually discredit Dumbledore, who along with Harry is the most prominent voice in the wizarding world attempting to warn of Voldemort's return, the Ministry appoints Dolores Umbridge as the High Inquisitor of Hogwarts. She transforms the school into a dictatorial regime and refuses to allow the students to learn ways to defend themselves against dark magic.[19]
Harry forms "Dumbledore's Army", a secret study group to teach his classmates the higher-level skills of Defence Against the Dark Arts that he has learned. An important prophecy concerning Harry and Voldemort is revealed,[20] and Harry discovers that he and Voldemort have a painful connection, allowing Harry to view some of Voldemort's actions telepathically. In the novel's climax, Harry and his friends face off against Voldemort's Death Eaters. Although the timely arrival of members of the Order of the Phoenix saves the children's lives, Sirius Black is killed in the conflict.[19]
In the sixth book, Harry Potter and the Half-Blood Prince, Voldemort begins waging open warfare. Harry and friends are relatively protected from that danger at Hogwarts. They are subject to all the difficulties of adolescence; Harry eventually begins dating Ginny Weasley. Near the beginning of the novel, Harry is given an old potions textbook filled with annotations and recommendations signed by a mysterious writer, "the Half-Blood Prince". This book is a source of scholastic success, but because of the potency of the spells that are written in it, becomes a source of concern. Harry takes private lessons with Dumbledore, who shows him various memories concerning the early life of Voldemort. These reveal that Voldemort, to preserve his life, has split his soul into pieces, creating a series of horcruxes, evil enchanted items hidden in various locations, one of which was the diary destroyed in the second book.[21] Harry's snobbish adversary, Draco Malfoy, attempts to attack Dumbledore, and the book culminates in the killing of Dumbledore by Professor Snape, the titular Half-Blood Prince.
Harry Potter and the Deathly Hallows, the last book in the series, begins directly after the events of the sixth book. Voldemort has completed his ascension to power and gains control of the Ministry of Magic. Harry, Ron, and Hermione drop out of school so that they can find and destroy Voldemort's remaining horcruxes. To ensure their own safety as well as that of their family and friends, they are forced to isolate themselves. As they search for the horcruxes, the trio learns details about Dumbledore's past, as well as Snape's true motives—he had worked on Dumbledore's behalf since the murder of Harry's mother.
The book culminates in the Battle of Hogwarts. Harry, Ron, and Hermione, in conjunction with members of the Order of the Phoenix and many of the teachers and students, defend Hogwarts from Voldemort, his Death Eaters, and various magical creatures. Several major characters are killed in the first wave of the battle. After learning that he himself is a horcrux, Harry surrenders himself to Voldemort, who casts a killing curse at him. However, the defenders of Hogwarts do not surrender after learning this, but continue to fight on. Having managed to return from the dead, Harry finally faces Voldemort, whose horcruxes have all been destroyed. In the subsequent battle, Voldemort's curse rebounds off of Harry's spell and kills Voldemort. An epilogue describes the lives of the surviving characters and the effects on the wizarding world.
Supplementary works

Rowling has expanded the Harry Potter universe with several short books produced for various charities.[22][23] In 2001, she released Fantastic Beasts and Where to Find Them (a purported Hogwarts textbook) and Quidditch Through the Ages (a book Harry reads for fun). Proceeds from the sale of these two books benefitted the charity Comic Relief.[24] In 2007, Rowling composed seven handwritten copies of The Tales of Beedle the Bard, a collection of fairy tales that is featured in the final novel, one of which was auctioned to raise money for the Children's High Level Group, a fund for mentally disabled children in poor countries. The book was published internationally on 4 December 2008.[25][26] Rowling also wrote an 800-word prequel in 2008 as part of a fundraiser organised by the bookseller Waterstones.[27] All three of these books contain extra information about the Wizarding World not included in the original novels. In 2011, Rowling launched a new website announcing an upcoming project called Pottermore.[28] Pottermore opened to the general public on 14 April 2012.[29] Pottermore allows users to be sorted, be chosen by their wand and play various minigames. The main purpose of the website however was to allow the user to journey though the story with access to content not revealed by JK Rowling previously, with over 18,000 words of additional content.[30]
Structure and genre

See also: Harry Potter influences and analogues
The Harry Potter novels fall within the genre of fantasy literature; however, in many respects they are also bildungsromans, or coming of age novels,[31] and contain elements of mystery, adventure, thriller, and romance. They can be considered part of the British children's boarding school genre, which includes Rudyard Kipling's Stalky & Co., Enid Blyton's Malory Towers, St. Clare's and the Naughtiest Girl series, and Frank Richards's Billy Bunter novels: the Harry Potter books are predominantly set in Hogwarts, a fictional British boarding school for wizards, where the curriculum includes the use of magic.[32] In this sense they are "in a direct line of descent from Thomas Hughes's Tom Brown's School Days and other Victorian and Edwardian novels of British public school life".[33][34] They are also, in the words of Stephen King, "shrewd mystery tales",[35] and each book is constructed in the manner of a Sherlock Holmes-style mystery adventure. The stories are told from a third person limited point of view with very few exceptions (such as the opening chapters of Philosopher's Stone, Goblet of Fire and Deathly Hallows and the first two chapters of Half-Blood Prince).
In the middle of each book, Harry struggles with the problems he encounters, and dealing with them often involves the need to violate some school rules. If students are caught breaking rules, they are often disciplined by Hogwarts professors. However, the stories reach their climax in the summer term, near or just after final exams, when events escalate far beyond in-school squabbles and struggles, and Harry must confront either Voldemort or one of his followers, the Death Eaters, with the stakes a matter of life and death–a point underlined, as the series progresses, by one or more characters being killed in each of the final four books.[36][37] In the aftermath, he learns important lessons through exposition and discussions with head teacher and mentor Albus Dumbledore. In the final novel, Harry Potter and the Deathly Hallows, Harry and his friends spend most of their time away from Hogwarts, and only return there to face Voldemort at the dénouement.[36]
Themes

According to Rowling, a major theme in the series is death: "My books are largely about death. They open with the death of Harry's parents. There is Voldemort's obsession with conquering death and his quest for immortality at any price, the goal of anyone with magic. I so understand why Voldemort wants to conquer death. We're all frightened of it."[6]
Academics and journalists have developed many other interpretations of themes in the books, some more complex than others, and some including political subtexts. Themes such as normality, oppression, survival, and overcoming imposing odds have all been considered as prevalent throughout the series.[38] Similarly, the theme of making one's way through adolescence and "going over one's most harrowing ordeals—and thus coming to terms with them" has also been considered.[39] Rowling has stated that the books comprise "a prolonged argument for tolerance, a prolonged plea for an end to bigotry" and that also pass on a message to "question authority and... not assume that the establishment or the press tells you all of the truth".[40]
While the books could be said to comprise many other themes, such as power/abuse of power, love, prejudice, and free choice, they are, as Rowling states, "deeply entrenched in the whole plot"; the writer prefers to let themes "grow organically", rather than sitting down and consciously attempting to impart such ideas to her readers.[7] Along the same lines is the ever-present theme of adolescence, in whose depiction Rowling has been purposeful in acknowledging her characters' sexualities and not leaving Harry, as she put it, "stuck in a state of permanent pre-pubescence".[41] Rowling said that, to her, the moral significance of the tales seems "blindingly obvious". The key for her was the choice between what is right and what is easy, "because that ... is how tyranny is started, with people being apathetic and taking the easy route and suddenly finding themselves in deep trouble."[42]
Origins and publishing history

J.K. Rowling, a blond, blue-eyed woman, who is the author of the series

The novelist, J. K. Rowling.
In 1990, Rowling was on a crowded train from Manchester to London when the idea for Harry suddenly "fell into her head". Rowling gives an account of the experience on her website saying:[43]
"I had been writing almost continuously since the age of six but I had never been so excited about an idea before. I simply sat and thought, for four (delayed train) hours, and all the details bubbled up in my brain, and this scrawny, black-haired, bespectacled boy who did not know he was a wizard became more and more real to me."
Rowling completed Harry Potter and the Philosopher's Stone in 1995 and the manuscript was sent off to several prospective agents.[44] The second agent she tried, Christopher Little, offered to represent her and sent the manuscript to Bloomsbury. After eight other publishers had rejected Philosopher's Stone, Bloomsbury offered Rowling a £2,500 advance for its publication.[45][46] Despite Rowling's statement that she did not have any particular age group in mind when beginning to write the Harry Potter books, the publishers initially targeted children aged nine to eleven.[47] On the eve of publishing, Rowling was asked by her publishers to adopt a more gender-neutral pen name in order to appeal to the male members of this age group, fearing that they would not be interested in reading a novel they knew to be written by a woman. She elected to use J. K. Rowling (Joanne Kathleen Rowling), using her grandmother's name as her second name because she has no middle name.[46][48]


The logo used in British editions
Harry Potter and the Philosopher's Stone was published by Bloomsbury, the publisher of all Harry Potter books in the United Kingdom, on 30 June 1997.[49] It was released in the United States on 1 September 1998 by Scholastic—the American publisher of the books—as Harry Potter and the Sorcerer's Stone,[50] after Rowling had received US$105,000 for the American rights—an unprecedented amount for a children's book by a then-unknown author.[51] Fearing that American readers would not associate the word "philosopher" with a magical theme (although the Philosopher's Stone is alchemy-related), Scholastic insisted that the book be given the title Harry Potter and the Sorcerer's Stone for the American market.
The second book, Harry Potter and the Chamber of Secrets was originally published in the UK on 2 July 1998 and in the US on 2 June 1999. Harry Potter and the Prisoner of Azkaban was then published a year later in the UK on 8 July 1999 and in the US on 8 September 1999.[52] Harry Potter and the Goblet of Fire was published on 8 July 2000 at the same time by Bloomsbury and Scholastic.[53] Harry Potter and the Order of the Phoenix is the longest book in the series at 766 pages in the UK version and 870 pages in the US version.[54] It was published worldwide in English on 21 June 2003.[55] Harry Potter and the Half-Blood Prince was published on 16 July 2005, and it sold 9 million copies in the first 24 hours of its worldwide release.[56][57] The seventh and final novel, Harry Potter and the Deathly Hallows, was published 21 July 2007.[58] The book sold 11 million copies in the first 24 hours of release, breaking down to 2.7 million copies in the UK and 8.3 million in the US.[57]
Translations
Main article: Harry Potter in translation
The series has been translated into 67 languages,[3][59] placing Rowling among the most translated authors in history.[60] The books have seen translations to diverse languages such as Azerbaijani, Ukrainian, Arabic, Urdu, Hindi, Bengali, Welsh, Afrikaans, Albanian, Latvian and Vietnamese. The first volume has been translated into Latin and even Ancient Greek,[61] making it the longest published work in Ancient Greek since the novels of Heliodorus of Emesa in the 3rd century AD.[62]
Some of the translators hired to work on the books were well-known authors before their work on Harry Potter, such as Viktor Golyshev, who oversaw the Russian translation of the series' fifth book. The Turkish translation of books two to seven was undertaken by Sevin Okyay, a popular literary critic and cultural commentator.[63] For reasons of secrecy, translation can only start when the books are released in English; thus there is a lag of several months before the translations are available. This has led to more and more copies of the English editions being sold to impatient fans in non-English speaking countries. Such was the clamour to read the fifth book that its English language edition became the first English-language book ever to top the best-seller list in France.[64]
The United States editions have been adapted into American English, to make them more understandable to a young American audience.[65]
Completion of the series
In December 2005, Rowling stated on her web site, "2006 will be the year when I write the final book in the Harry Potter series."[66] Updates then followed in her online diary chronicling the progress of Harry Potter and the Deathly Hallows, with the release date of 21 July 2007. The book itself was finished on 11 January 2007 in the Balmoral Hotel, Edinburgh, where she scrawled a message on the back of a bust of Hermes. It read: "J. K. Rowling finished writing Harry Potter and the Deathly Hallows in this room (552) on 11 January 2007."[67]
Rowling herself has stated that the last chapter of the final book (in fact, the epilogue) was completed "in something like 1990".[68][69] In June 2006, Rowling, on an appearance on the British talk show Richard & Judy, announced that the chapter had been modified as one character "got a reprieve" and two others who previously survived the story had in fact been killed. On 28 March 2007, the cover art for the Bloomsbury Adult and Child versions and the Scholastic version were released.[70][71]
In September 2012, Rowling mentioned in an interview that she might go back to make a "director's cut" of two of the existing Harry Potter books.[72]

Fans of the series were so eager for the latest instalment that bookstores around the world began holding events to coincide with the midnight release of the books, beginning with the 2000 publication of Harry Potter and the Goblet of Fire. The events, commonly featuring mock sorting, games, face painting, and other live entertainment have achieved popularity with Potter fans and have been highly successful in attracting fans and selling books with nearly nine million of the 10.8 million initial print copies of Harry Potter and the Half-Blood Prince sold in the first 24 hours.[73][74] The final book in the series, Harry Potter and the Deathly Hallows became the fastest selling book in history, moving 11 million units in the first twenty-four hours of release.[75] The series has also gathered adult fans, leading to the release of two editions of each Harry Potter book, identical in text but with one edition's cover artwork aimed at children and the other aimed at adults.[76] Besides meeting online through blogs, podcasts, and fansites, Harry Potter super-fans can also meet at Harry Potter symposia.
The word Muggle has spread beyond its Harry Potter origins, becoming one of few pop culture words to land in the Oxford English Dictionary.[77] The Harry Potter fandom has embraced podcasts as a regular, often weekly, insight to the latest discussion in the fandom. Both MuggleCast and PotterCast[78] have reached the top spot of iTunes podcast rankings and have been polled one of the top 50 favourite podcasts.[79]

The popularity of the Harry Potter series has translated into substantial financial success for Rowling, her publishers, and other Harry Potter related license holders. This success has made Rowling the first and thus far only billionaire author.[80] The books have sold more than 400 million copies worldwide and have also given rise to the popular film adaptations produced by Warner Bros., all of which have been highly successful in their own right.[4][81] The films have in turn spawned eight video games and have led to the licensing of more than 400 additional Harry Potter products (including an iPod). The Harry Potter brand has been estimated to be worth as much as $15 billion.[8]
The great demand for Harry Potter books motivated the New York Times to create a separate best-seller list for children's literature in 2000, just before the release of Harry Potter and the Goblet of Fire. By 24 June 2000, Rowling's novels had been on the list for 79 straight weeks; the first three novels were each on the hardcover best-seller list.[82] On 12 April 2007, Barnes & Noble declared that Deathly Hallows had broken its pre-order record, with more than 500,000 copies pre-ordered through its site.[83] For the release of Goblet of Fire, 9,000 FedEx trucks were used with no other purpose than to deliver the book.[84] Together, Amazon.com and Barnes & Noble pre-sold more than 700,000 copies of the book.[84] In the United States, the book's initial printing run was 3.8 million copies.[84] This record statistic was broken by Harry Potter and the Order of the Phoenix, with 8.5 million, which was then shattered by Half-Blood Prince with 10.8 million copies.[85] 6.9 million copies of Prince were sold in the U.S. within the first 24 hours of its release; in the United Kingdom more than two million copies were sold on the first day.[86] The initial U.S. print run for Deathly Hallows was 12 million copies, and more than a million were pre-ordered through Amazon and Barnes & Noble.[87]
Awards, honours, and recognition
The Harry Potter series have been the recipients of a host of awards since the initial publication of Philosopher's Stone including four Whitaker Platinum Book Awards (all of which were awarded in 2001),[88] three Nestlé Smarties Book Prizes (1997–1999),[89] two Scottish Arts Council Book Awards (1999 and 2001),[90] the inaugural Whitbread children's book of the year award (1999),[91] the WHSmith book of the year (2006),[92] among others. In 2000, Harry Potter and the Prisoner of Azkaban was nominated for a Hugo Award for Best Novel, and in 2001, Harry Potter and the Goblet of Fire won said award.[93] Honours include a commendation for the Carnegie Medal (1997),[94] a short listing for the Guardian Children's Award (1998), and numerous listings on the notable books, editors' Choices, and best books lists of the American Library Association, The New York Times, Chicago Public Library, and Publishers Weekly.[95]
A 2004 study found that books in the series were commonly read aloud in elementary schools in San Diego County, California.[96] Based on a 2007 online poll, the National Education Association in the U.S. listed the series in its "Teachers' Top 100 Books for Children."[97] Three of the books (Sorcerer’s Stone, Prisoner of Azkaban, and Goblet of Fire) were among the "Top 100 Chapter Books" of all time in a 2012 poll by School Library Journal.[98]

Early in its history, Harry Potter received positive reviews. On publication, the first volume, Harry Potter and the Philosopher's Stone, attracted attention from the Scottish newspapers, such as The Scotsman, which said it had "all the makings of a classic",[99] and The Glasgow Herald, which called it "Magic stuff".[99] Soon the English newspapers joined in, with more than one comparing it to Roald Dahl's work: The Mail on Sunday rated it as "the most imaginative debut since Roald Dahl",[99] a view echoed by The Sunday Times ("comparisons to Dahl are, this time, justified"),[99] while The Guardian called it "a richly textured novel given lift-off by an inventive wit".[99]
By the time of the release of the fifth volume, Harry Potter and the Order of the Phoenix, the books began to receive strong criticism from a number of literary scholars. Yale professor, literary scholar, and critic Harold Bloom raised criticisms of the books' literary merits, saying, "Rowling's mind is so governed by clichés and dead metaphors that she has no other style of writing."[100] A. S. Byatt authored a New York Times op-ed article calling Rowling's universe a "secondary secondary world, made up of intelligently patchworked derivative motifs from all sorts of children's literature ... written for people whose imaginative lives are confined to TV cartoons, and the exaggerated (more exciting, not threatening) mirror-worlds of soaps, reality TV and celebrity gossip".[101]
Michael Rosen, a novelist and poet, advocated the books were not suited for children, who would be unable to grasp the complex themes. Rosen also stated that "J. K. Rowling is more of an adult writer."[102] The critic Anthony Holden wrote in The Observer on his experience of judging Harry Potter and the Prisoner of Azkaban for the 1999 Whitbread Awards. His overall view of the series was negative—"the Potter saga was essentially patronising, conservative, highly derivative, dispiritingly nostalgic for a bygone Britain", and he speaks of "pedestrian, ungrammatical prose style".[103] Ursula Le Guin said, "I have no great opinion of it. When so many adult critics were carrying on about the 'incredible originality' of the first Harry Potter book, I read it to find out what the fuss was about, and remained somewhat puzzled; it seemed a lively kid's fantasy crossed with a "school novel", good fare for its age group, but stylistically ordinary, imaginatively derivative, and ethically rather mean-spirited."[104]
By contrast, author Fay Weldon, while admitting that the series is "not what the poets hoped for", nevertheless goes on to say, "but this is not poetry, it is readable, saleable, everyday, useful prose".[105] The literary critic A. N. Wilson praised the Harry Potter series in The Times, stating: "There are not many writers who have JK's Dickensian ability to make us turn the pages, to weep—openly, with tears splashing—and a few pages later to laugh, at invariably good jokes ... We have lived through a decade in which we have followed the publication of the liveliest, funniest, scariest and most moving children's stories ever written".[106] Charles Taylor of Salon.com, who is primarily a movie critic,[107] took issue with Byatt's criticisms in particular. While he conceded that she may have "a valid cultural point—a teeny one—about the impulses that drive us to reassuring pop trash and away from the troubling complexities of art",[108] he rejected her claims that the series is lacking in serious literary merit and that it owes its success merely to the childhood reassurances it offers. Taylor stressed the progressively darker tone of the books, shown by the murder of a classmate and close friend and the psychological wounds and social isolation each causes. Taylor also argued that Philosopher's Stone, said to be the most light-hearted of the seven published books, disrupts the childhood reassurances that Byatt claims spur the series' success: the book opens with news of a double murder, for example.[108]
Stephen King called the series "a feat of which only a superior imagination is capable", and declared "Rowling's punning, one-eyebrow-cocked sense of humor" to be "remarkable". However, he wrote that despite the story being "a good one", he is "a little tired of discovering Harry at home with his horrible aunt and uncle", the formulaic beginning of all seven books.[35] King has also joked that "Rowling's never met an adverb she did not like!" He does however predict that Harry Potter "will indeed stand time's test and wind up on a shelf where only the best are kept; I think Harry will take his place with Alice, Huck, Frodo, and Dorothy and this is one series not just for the decade, but for the ages".[109]
Social impacts
Although Time magazine named Rowling as a runner-up for its 2007 Person of the Year award, noting the social, moral, and political inspiration she has given her fandom,[110] cultural comments on the series have been mixed. Washington Post book critic Ron Charles opined in July 2007 that the large numbers of adults reading the Potter series but few other books may represent a "bad case of cultural infantilism", and that the straightforward "good vs. evil" theme of the series is "childish". He also argued "through no fault of Rowling's", the cultural and marketing "hysteria" marked by the publication of the later books "trains children and adults to expect the roar of the coliseum, a mass-media experience that no other novel can possibly provide".[111]
Librarian Nancy Knapp pointed out the books' potential to improve literacy by motivating children to read much more than they otherwise would.[112] Agreeing about the motivating effects, Diane Penrod also praised the books' blending of simple entertainment with "the qualities of highbrow literary fiction", but expressed concern about the distracting effect of the prolific merchandising that accompanies the book launches.[113]
Jennifer Conn used Snape's and Quidditch coach Madam Hooch's teaching methods as examples of what to avoid and what to emulate in clinical teaching,[114] and Joyce Fields wrote that the books illustrate four of the five main topics in a typical first-year sociology class: "sociological concepts including culture, society, and socialisation; stratification and social inequality; social institutions; and social theory".[115]
Jenny Sawyer wrote in Christian Science Monitor on 25 July 2007 that the books represent a "disturbing trend in commercial storytelling and Western society" in that stories "moral center [sic] have all but vanished from much of today's pop culture ... after 10 years, 4,195 pages, and over 375 million copies, J. K. Rowling's towering achievement lacks the cornerstone of almost all great children's literature: the hero's moral journey". Harry Potter, Sawyer argues, neither faces a "moral struggle" nor undergoes any ethical growth, and is thus "no guide in circumstances in which right and wrong are anything less than black and white".[116] In contrast Emily Griesinger described Harry's first passage through to Platform 9¾ as an application of faith and hope, and his encounter with the Sorting Hat as the first of many in which Harry is shaped by the choices he makes. She also noted the "deeper magic" by which the self-sacrifice of Harry's mother protects the boy throughout the series, and which the power-hungry Voldemort fails to understand.[117]
In an 8 November 2002 Slate article, Chris Suellentrop likened Potter to a "trust-fund kid whose success at school is largely attributable to the gifts his friends and relatives lavish upon him". Noting that in Rowling's fiction, magical ability potential is "something you are born to, not something you can achieve", Suellentrop wrote that Dumbledore's maxim that "It is our choices that show what we truly are, far more than our abilities" is hypocritical, as "the school that Dumbledore runs values native gifts above all else".[118] In a 12 August 2007 New York Times review of Deathly Hallows, however, Christopher Hitchens praised Rowling for "unmooring" her "English school story" from literary precedents "bound up with dreams of wealth and class and snobbery", arguing that she had instead created "a world of youthful democracy and diversity".[119]
Controversies
Main articles: Legal disputes over the Harry Potter series, Religious debates over the Harry Potter series, Politics of Harry Potter, and Tanya Grotter
The books have been the subject of a number of legal proceedings, stemming either from claims by American Christian groups that the magic in the books promotes Wicca and witchcraft among children, or from various conflicts over copyright and trademark infringements. The popularity and high market value of the series has led Rowling, her publishers, and film distributor Warner Bros. to take legal measures to protect their copyright, which have included banning the sale of Harry Potter imitations, targeting the owners of websites over the "Harry Potter" domain name, and suing author Nancy Stouffer to counter her accusations that Rowling had plagiarised her work.[120][121][122] Various religious conservatives have claimed that the books promote witchcraft and religions such as Wicca and are therefore unsuitable for children,[123][124] while a number of critics have criticised the books for promoting various political agendas.[125][126]
The books also aroused controversies in the literary and publishing worlds. In 1997 to 1998, Harry Potter and the Philosopher's Stone won almost all the UK awards judged by children, but none of the children's book awards judged by adults,[127] and Sandra Beckett suggested the reason was intellectual snobbery towards books that were popular among children.[128] In 1999, the winner of the Whitbread Book of the Year Award children's division was entered for the first time on the shortlist for the main award, and one judge threatened to resign if Harry Potter and the Prisoner of Azkaban was declared the overall winner; it finished second, very close behind the winner of the poetry prize, Seamus Heaney's translation of the Anglo-Saxon epic Beowulf.[128]
In 2000, shortly before the publication of Harry Potter and the Goblet of Fire, the previous three Harry Potter books topped the New York Times fiction best-seller list and a third of the entries were children's books. The newspaper created a new children's section covering children's books, including both fiction and non-fiction, and initially counting only hardback sales. The move was supported by publishers and booksellers.[82] In 2004, The New York Times further split the children's list, which was still dominated by Harry Potter books into sections for series and individual books, and removed the Harry Potter books from the section for individual books.[129] The split in 2000 attracted condemnation, praise and some comments that presented both benefits and disadvantages of the move.[130] Time suggested that, on the same principle, Billboard should have created a separate "mop-tops" list in 1964 when the Beatles held the top five places in its list, and Nielsen should have created a separate game-show list when Who Wants to Be a Millionaire? dominated the ratings.[131]

In 1998, Rowling sold the film rights of the first four Harry Potter books to Warner Bros. for a reported £1 million ($1,982,900).[132][133] Rowling demanded the principal cast be kept strictly British, nonetheless allowing for the inclusion of Irish actors such as the late Richard Harris as Dumbledore, and for casting of French and Eastern Europe actors in Harry Potter and the Goblet of Fire where characters from the book are specified as such.[134] After many directors including Steven Spielberg, Terry Gilliam, Jonathan Demme, and Alan Parker were considered, Chris Columbus was appointed on 28 March 2000 as director for Harry Potter and the Philosopher's Stone (titled "Harry Potter and the Sorcerer's Stone" in the United States), with Warner Bros. citing his work on other family films such as Home Alone and Mrs. Doubtfire and proven experience with directing children as influences for their decision.[135]
After extensive casting, filming began in October 2000 at Leavesden Film Studios and in London itself, with production ending in July 2001.[136][137] Philosopher's Stone was released on 14 November 2001. Just three days after the film's release, production for Harry Potter and the Chamber of Secrets, also directed by Columbus, began. Filming was completed in summer 2002, with the film being released on 15 November 2002.[138] Daniel Radcliffe portrayed Harry Potter, doing so for all succeeding films in the franchise.
Columbus declined to direct Harry Potter and the Prisoner of Azkaban, only acting as producer. Mexican director Alfonso Cuarón took over the job, and after shooting in 2003, the film was released on 4 June 2004. Due to the fourth film beginning its production before the third's release, Mike Newell was chosen as the director for Harry Potter and the Goblet of Fire, released on 18 November 2005.[139] Newell became the first British director of the series, with television director David Yates following suit after he was chosen to helm Harry Potter and the Order of the Phoenix. Production began in January 2006 and the film was released the following year in July 2007.[140] After executives were "really delighted" with his work on the film, Yates was selected to direct Harry Potter and the Half-Blood Prince, which was released on 15 July 2009.[141][142][143][144]

In March 2008, Warner Bros. President and COO Alan F. Horn announced that the final instalment in the series, Harry Potter and the Deathly Hallows, would be released in two cinematic parts: Part 1 on 19 November 2010 and Part 2 on 15 July 2011. Production of both parts started in February 2009, with the final day of principal photography taking place on 12 June 2010.[145][146]
Rowling had creative control on the film series, observing the filmmaking process of Philosopher's Stone and serving as producer on the two-part Deathly Hallows, alongside David Heyman and David Barron.[147] The Harry Potter films have been top-rank box office hits, with all eight releases on the list of highest-grossing films worldwide. Philosopher's Stone was the highest-grossing Harry Potter film up until the release of the final installment of the series, Deathly Hallows, while Prisoner of Azkaban grossed the least.[148] As well as being a financial success, the film series has also been a success among film critics.[149][150]
Opinions of the films are generally divided among fans, with one group preferring the more faithful approach of the first two films, and another group preferring the more stylised character-driven approach of the later films.[151] Rowling has been constantly supportive of all the films and evaluated Deathly Hallows as her "favourite one" in the series.[152][153][154][155] She wrote on her website of the changes in the book-to-film transition, "It is simply impossible to incorporate every one of my storylines into a film that has to be kept under four hours long. Obviously films have restrictions novels do not have, constraints of time and budget; I can create dazzling effects relying on nothing but the interaction of my own and my readers' imaginations".[156]
At the 64th British Academy Film Awards in February 2011, Rowling was joined by producers David Heyman and David Barron along with directors David Yates, Alfonso Cuarón and Mike Newell in collecting the Michael Balcon Award for Outstanding British Contribution to Cinema on behalf of all the films in the series. Actors Rupert Grint and Emma Watson, who play main characters Ron Weasley and Hermione Granger, were also in attendance.[157][158]
Games
There are eleven Harry Potter video games, eight of which correspond with the films and books, and three other spin-offs. The film/book based games are produced by Electronic Arts, as was Harry Potter: Quidditch World Cup, with the game version of the first entry in the series, Philosopher's Stone, being released in November 2001. The video games are released to coincide with the films, containing scenery and details from the films as well as the tone and spirit of the books. Objectives usually occur in and around Hogwarts, along with various other magical areas. The story and design of the games follows the selected film's characterisation and plot; EA worked closely with Warner Brothers to include scenes from the films. The last game in the series, Deathly Hallows, was split with Part 1 released in November 2010 and Part 2 debuting on consoles in July 2011. The two-part game forms the first entry to convey an intense theme of action and violence, with the gameplay revolving around a third-person shooter style format.[159][160] The other spin-offs games, LEGO Harry Potter: Years 1–4 and LEGO Harry Potter: Years 5–7 are developed by Traveller's Tales and published by Warner Bros. Interactive Entertainment. A number of other non-interactive media games have been released; board games such as Cluedo Harry Potter Edition, Scene It? Harry Potter and Lego Harry Potter models, which are influenced by the themes of both the novels and films.

In her statement, the author said that the play will "explore the previously untold story of Harry's early years as an orphan and outcast." British theater producers Sonia Friedman and Colin Callender will be the co-producers.[163][164]
Attractions

United States
Main article: The Wizarding World of Harry Potter (Islands of Adventure)


Hogwarts Castle as depicted in the Wizarding World of Harry Potter located in Universal Orlando Resort's Island of Adventure.
After the success of the films and books, Universal and Warner Brothers announced they would create "The Wizarding World of Harry Potter," a new Harry Potter-themed expansion to the Islands of Adventure theme park at Universal Orlando Resort in Florida. The new land, promoted as the seventh themed "island" of the park, was built from land reserved for expansion outside of the park's original border, as well as from much of the existing "island," The Lost Continent. A soft opening was held at the end of March 2010, with the land opening on 16 June 2010 for reserved guests. The land officially opened to the public on 18 June 2010.[165]
Guests enter the land through a recreation of the Hogsmeade station,[166] leading into the village of Hogsmeade, with a forced-perspective Hogwarts castle at the very end of the street. The castle contains the expansion's centrepiece attraction, Harry Potter & the Forbidden Journey, a KUKA arm attraction which takes passengers through many realistic scenes influenced by the movies and books, including soaring over Hogwarts, getting involved in a Quidditch match, and having close encounters with dragons, dementors, and the Whomping Willow.[167] Other attractions include a twin high-speed rollercoaster named the Dragon Challenge, a renovation of the previously existing rollercoaster, Dueling Dragons, and a family roller coaster called Flight of the Hippogriff, a renovation of the previously existing ride, Flying Unicorn. In addition to the three rides are several themed shops and restaurants, heavily inspired by their appearances in the books and films: Honeydukes sells sweets, such as chocolate frogs and Bertie Bott's Every-Flavour Beans, Ollivander's offers personalised magic wands, Zonko's Joke Shop sells various items including Sneakoscopes, and the Three Broomsticks serves food and drink, most notably Butterbeer and pumpkin juice.
Developed at a cost of $265 million, the new land "has seen capacity crowds [and] waits of up to two hours just to enter the ... merchandise shop." Islands of Adventure saw a massive increase in attendance following the expansion, seeing gains of as much as 36%,[168] a period during which attendance to competitor resort Walt Disney World dropped slightly.[169] Disney had itself entered negotiations for a Harry Potter-themed expansion, but ultimately turned down the opportunity.[170]
United Kingdom
In March 2011, Warner Bros. announced plans to build a tourist attraction in the United Kingdom to showcase the Harry Potter film series. Warner Bros. Studio Tour London is a behind-the-scenes walking tour featuring authentic sets, costumes and props from the film series. The attraction is located at Warner Bros. Studios, Leavesden, where all eight of the Harry Potter films were made. Warner Bros. constructed two new sound stages to house and showcase the famous sets from each of the British-made productions, following a £100 million investment.[171] It opened to the public in March 2012HERO DYD

iPhone



The iPhone (/ˈaɪfoʊn/ eye-fohn) is a line of smartphones designed and marketed by Apple Inc. It runs Apple's iOS mobile operating system.[14] The first generation iPhone was released on June 29, 2007; the most recent iPhones, the seventh-generation iPhone 5C and iPhone 5S, were introduced on September 10, 2013.
The user interface is built around the device's multi-touch screen, including a virtual keyboard. The iPhone has Wi-Fi and can connect to many different cellular networks, including 1xRTT and GPRS (shown as a circle on the status bar), EDGE (shown as a capital E on the status bar), UMTS and EV-DO (shown as 3G), a faster version of UMTS and 4G (shown as a 4G symbol on the status bar), and LTE (shown as LTE on the status bar).[15] An iPhone can shoot video (though this was not a standard feature until the iPhone 3GS), take photos, play music, send and receive email, browse the web, send texts, GPS navigation, tell jokes, record notes, do mathematical calculations, and receive visual voicemail.[16] Other functions — video games, reference works, social networking, etc. — can be enabled by downloading application programs (‘apps’); as of October 2013, the App Store offered more than one million apps by Apple and third parties.[17]
There are seven generations of iPhone models, each accompanied by one of the six major releases of iOS. The original 1st-generation iPhone was a GSM phone and established design precedents, such as a button placement that has persisted through all models and a screen size maintained for the next four iterations. The iPhone 3G added 3G cellular network capabilities and A-GPS location. The iPhone 3GS added a faster processor and a higher-resolution camera that could record video at 480p. The iPhone 4 featured a higher-resolution 960×640 "Retina Display", a VGA front-facing camera for video calling and other apps, and a 5-megapixel rear-facing camera with 720p video capture.[18] The iPhone 4S upgrades to an 8-megapixel camera with 1080p video recording, a dual-core A5 processor, and a natural language voice control system called Siri.[19] iPhone 5 features the dual-core A6 processor, increases the size of the Retina display to 4 inches, and replaces the 30-pin connector with an all-digital Lightning connector. The iPhone 5S features the dual-core 64-bit A7 processor, an updated camera with a larger aperture and dual-LED flash, and the Touch ID fingerprint scanner, integrated into the home button. iPhone 5C features the same A6 chip as the iPhone 5, along with a new backside-illuminated FaceTime camera and a new
casing made of polycarbonate. As of 2013, the iPhone 3GS had the longest production run, 1181 days; followed by the iPhone 4, produced for 1174 days.[20]
The resounding sales of the iPhone have been credited with reshaping the smartphone industry and helping make Apple one of the world's most valuable publicly traded companies in 2011–12.[21] The iPhone is the top-selling phone of any kind in some countries, including the United States[22] and Japan.[23]

Main article: History of the iPhone
See also: List of iOS devices
Development of what was to become the iPhone began in 2004, when Apple started to gather a team of 1000 employees to work on the highly confidential "Project Purple",[24] including Sir Jonathan Ive, the designer behind the iPhone.[25] Apple CEO Steve Jobs steered the original focus away from a tablet, like the iPad, and towards a phone.[26] Apple created the device during a secretive collaboration with AT&T Mobility—Cingular Wireless at the time—at an estimated development cost of US$150 million over thirty months.[27]
Apple rejected the "design by committee" approach that had yielded the Motorola ROKR E1, a largely unsuccessful[28] collaboration with Motorola. Instead, Cingular gave Apple the liberty to develop the iPhone's hardware and software in-house[29][30] and even paid Apple a fraction of its monthly service revenue (until the iPhone 3G),[31] in exchange for four years of exclusive US sales, until 2011.
Jobs unveiled the iPhone to the public on January 9, 2007, at the Macworld 2007 convention at the Moscone Center in San Francisco.[32] The two initial models, a 4 GB model priced at US$ 499 and an 8 GB model at US$ 599, went on sale in the United States on June 29, 2007, at 6:00 pm local time, while hundreds of customers lined up outside the stores nationwide.[33] The passionate reaction to the launch of the iPhone resulted in sections of the media dubbing it the 'Jesus phone'.[34][35] The first generation iPhone was made available in the UK, France, and Germany in November 2007, and Ireland and Austria in the spring of 2008.


Worldwide iPhone availability:
  iPhone available since its original release
  iPhone available since the release of iPhone 3G
  Coming soon
On July 11, 2008, Apple released the iPhone 3G in twenty-two countries, including the original six.[36] Apple released the iPhone 3G in upwards of eighty countries and territories.[37] Apple announced the iPhone 3GS on June 8, 2009, along with plans to release it later in June, July, and August, starting with the US, Canada and major European countries on June 19. Many would-be users objected to the iPhone's cost,[38] and 40% of users have household incomes over US$100,000.[39]
The back of the original first generation iPhone was made of aluminum with a black plastic accent. The iPhone 3G and 3GS feature a full plastic back to increase the strength of the GSM signal.[40] The iPhone 3G was available in an 8 GB black model, or a black or white option for the 16 GB model. The iPhone 3GS was available in both colors, regardless of storage capacity.
The iPhone 4 has an aluminosilicate glass front and back with a stainless steel edge that serves as the antennas. It was at first available in black; the white version was announced, but not released until April 2011, 10 months later.
The iPhone has garnered positive reviews from such critics as David Pogue[41] and Walt Mossberg.[42][43] The iPhone attracts users of all ages,[39] and besides consumer use, the iPhone has also been adopted for business purposes.[44]
Users of the iPhone 4 reported dropped/disconnected telephone calls when holding their phones in a certain way. This became known as antennagate.[45]
On January 11, 2011, Verizon announced during a media event that it had reached an agreement with Apple and would begin selling a CDMA2000 iPhone 4. Verizon said it would be available for pre-order on February 3, with a release set for February 10.[46][47] In February 2011, the Verizon iPhone accounted for 4.5% of all iPhone ad impressions[vague] in the US on Millennial Media's mobile ad network.[48]
From 2007 to 2011, Apple spent $647 million on advertising for the iPhone in the US.[24]
On Tuesday, September 27, Apple sent invitations for a press event to be held October 4, 2011, at 10:00 am at the Cupertino Headquarters to announce details of the next generation iPhone, which turned out to be iPhone 4S. Over 1 million 4S models were sold in the first 24 hours after its release in October 2011.[49] Due to large volumes of the iPhone being manufactured and its high selling price, Apple became the largest mobile handset vendor in the world by revenue, in 2011, surpassing long-time leader Nokia.[50] American carrier C Spire Wireless announced that it would be carrying the iPhone 4S on October 19, 2011.[51]
In January 2012, Apple reported its best quarterly earnings ever, with 53% of its revenue coming from the sale of 37 million iPhones, at an average selling price of nearly $660. The average selling price has remained fairly constant for most of the phone's lifespan, hovering between $622 and $660.[52] The production price of the iPhone 4S was estimated by IHS iSuppli, in October 2011, to be $188, $207 and $245, for the 16 GB, 32 GB and 64 GB models, respectively.[53] Labor costs are estimated at between $12.5 and $30 per unit, with workers on the iPhone assembly line making $1.78 an hour.[54]
In February 2012, ComScore reported that 12.4% of US mobile subscribers use an iPhone.[55] Approximately 6.4 million iPhones are active in the US alone.[39]
On September 12, 2012, Apple announced the iPhone 5. It has a 4-inch display, up from its predecessors' 3.5-inch screen. The device comes with the same 326 pixels per inch found in the iPhone 4 and 4S. The iPhone 5 has the soc A6 processor, the chip is 22% smaller than the iPhone 4S' A5 and is twice as fast, doubling the graphics performance of its predecessor. The device is 18% thinner than the iPhone 4S, measuring 7.6 mm, and is 20% lighter at 112 grams.
On July 6, 2013, it was reported that Apple was in talks with Korean mobile carrier, SK Telecom, to release the next generation iPhone with LTE Advanced technology.[56]
On July 22, 2013 the company's suppliers said that Apple is testing out larger screens for the iPhone and iPad. "Apple has asked for prototype smartphone screens larger than 4 inches and has also asked for screen designs for a new tablet device measuring slightly less than 13 inches diagonally, they said."[57]
On September 10, 2013, Apple unveiled two new iPhone models during a highly anticipated press event in Cupertino, California, U.S. The iPhone 5C, a mid-range-priced version of the handset that is designed to increase accessibility due its price, is available in five colors (green, blue, yellow, pink, and white) and is made of plastic. The iPhone 5S comes in three colors (black, white, and gold) and the home button is replaced with a fingerprint scanner. Both phones shipped on September 20, 2013.[58]
Sales and profits
For additional sales information, see the table of quarterly sales.
Apple sold 6.1 million first generation iPhone units over five quarters.[59] Sales in Q4 2008 surpassed temporarily those of Research In Motion's (RIM) BlackBerry sales of 5.2 million units, which made Apple briefly the third largest mobile phone manufacturer by revenue, after Nokia and Samsung[60] (it must be noted that some of this income is deferred[61]). Recorded sales grew steadily thereafter, and by the end of fiscal year 2010, a total of 73.5 million iPhones were sold.[62]
By 2010, the iPhone had a market share of barely 4% of all cellphones, however Apple pulled in more than 50% of the total profit that global cellphone sales generate.[63] Apple sold 14.1 million iPhones in Q3 2010, representing a 91% unit growth over the year-ago quarter, which was well ahead of IDC’s latest published estimate of 64% growth for the global smartphone market in the September quarter. Apple's sales surpassed that of Research in Motion’s 12.1 million BlackBerry units sold in their most recent quarter ended August 2010.[4] In the United States market alone for Q3 2010, while there were 9.1 million Android-powered smartphones shipped for 43.6% of the market, Apple iOS was the number two phone operating system with 26.2% but the 5.5 million iPhones sold made it the most popular single device.[64]
On March 2, 2011, at the iPad 2 launch event, Apple announced that they had sold 100 million iPhones worldwide.[65] As a result of the success of the iPhone sales volume and high selling price, headlined by the iPhone 4S, Apple became the largest mobile handset vendor in the world by revenue in 2011, surpassing long-time leader Nokia.[50] While the Samsung Galaxy S II has proven more popular than the iPhone 4S in parts of Europe, the iPhone 4S is dominant in the United States.[66]
In January 2012, Apple reported its best quarterly earnings ever, with 53% of its revenue coming from the sale of 37 million iPhones, at an average selling price of nearly $660. The average selling price has remained fairly constant for most of the phones lifespan, hovering between $622 and $660.[52]
For the eight largest phone manufacturers in Q1 2012, according to Horace Dediu at Asymco, Apple and Samsung combined to take 99% of industry profits (HTC took the remaining 1%, while RIM, LG, Sony Ericsson, Motorola, and Nokia all suffered losses), with Apple earning 73 cents out of every dollar earned by the phone makers. As the industry profits grew from $5.3 billion in Q1, 2010 to $14.4 billion in Q1, 2012 (quadruple the profits in 2007),[67][68] Apple had managed to increase its share of these profits. This is due to increasing carrier subsidies and the high selling prices of the iPhone, which had a negative effect on the wireless carriers (AT&T Mobility, Verizon, and Sprint) who have seen their EBITDA service margins drop as they sold an increasing number of iPhones.[69][70][71] By the quarter ended March 31, 2012, Apple's sales from the iPhone alone (at $22.7 billion) exceeded the total of Microsoft from all of its businesses ($17.4 billion).[72]
In Q4 2012, the iPhone 5 and iPhone 4S were the best-selling handsets with sales of 27.4 million (13% of smartphones worldwide) and 17.4 million units, respectively, with the Samsung Galaxy S III in third with 15.4 million. According to Strategy Analytics’ data, this was an ”an impressive performance, given the iPhone portfolio’s premium pricing”, adding that the Galaxy SIII’s global popularity “appears to have peaked” (the Galaxy S III was touted as an iPhone-killer by some in the press when it was released[73][74]). While Samsung has led in worldwide sales of smartphones, Apple's iPhone line has still managed to top Samsung's smartphone offerings in the United States,[75] with 21.4% share and 37.8% in that market, respectively. iOS grew 3.5% to a 37.8%, while Android slid 1.3% to fall to 52.3% share.[76]
The continued top popularity of the iPhone despite growing Android competition was also attributed to Apple being able to deliver iOS updates over the air, while Android updates are frequently impeded by carrier testing requirements and hardware tailoring, forcing consumers to purchase new Android smartphone in order to get the latest version of that OS.[77] However by 2013 Apple's market share had fallen to 13.1%, due to the surging popularity of the Android offerings, and as the iPhone does not compete in the feature phone or prepaid segments.[78]
Apple announced on September 1, 2013, that its iPhone trade-in program would be implemented at all of its 250 specialty stores in the US. For the program to become available, customers must have a valid contract and must purchase a new phone, rather than simply receive credit to be used at a later date. A significant part of the program's goal is to increase the number of customers who purchase iPhones at Apple stores rather than carrier stores.[79]
On September 20, 2013, the sales date of the iPhone 5s and 5c models, the longest ever queue was observed at the New York City, US flagship Apple store, in addition to prominent queues in San Francisco, US and Canada; however, locations throughout the world were identified for the anticipation of corresponding consumers.[80] Apple also increased production of the gold-colored iPhone 5S by an additional one-third due to the particularly strong demand that emerged.[81]
Apple released its opening weekend sales results for the 5c and 5s models, showing an all-time high for the product's sales figures, with 9 million handsets sold—the previous record was set in 2012, when 5 million handsets were sold during the opening weekend of the 5 model. This was the first time that Apple has simultaneously launched two models and the inclusion of China in the list of markets contributed to the record sales result.[82] Apple also announced that, as of September 23, 2013, 200 million devices were running the iOS 7 update, making it the “fastest software upgrade in history."[83]
An Apple Store located at the Christiana Mall in Newark, Delaware, US claimed the highest iPhones sales figures in November 2013. The store's high sales results are due to the absence of a sales tax in the state of Delaware.[84]
The finalization of a deal between Apple and China Mobile, the world's largest mobile network, was announced in late December 2013. The multi-year agreement provides iPhone access to over 760 million China Mobile subscribers.[85]
Legacy
Before the release of the iPhone, handset manufacturers such as Nokia and Motorola were enjoying record sales of cell phones based more on fashion and brand rather than technological innovation.[86] The smartphone market, dominated at the time by BlackBerry OS and Windows Mobile devices, was a "staid, corporate-led smartphone paradigm" focused on enterprise needs. Phones at the time were designed around carrier and business limits which were conservative with regards to bandwidth usage and battery life.[87][88]
When then-CEO of Research in Motion Mike Lazaridis pried open an iPhone, he described it as "like Apple had stuffed a Mac computer into a cellphone", as it used much more memory and processing power than the smartphones on the market at the time.[87][88] With its capacitive touchscreen and consumer-friendly design, the iPhone fundamentally changed the mobile industry, with Steve Jobs proclaiming in 2007 that "the phone was not just a communication tool but a way of life".[89]
The dominant mobile operating systems at the time such as Symbian, BlackBerry OS, and Windows Mobile were not designed to handle additional tasks beyond communication and basic functions; iPhone OS (renamed iOS in 2010) was designed as a robust OS with capabilities such as multitasking and graphics in order to meet future consumer demands.[90] These operating systems never focused on applications and developers, and due to infighting among manufacturers as well as the complex bureaucracy and bloatness of the OS, they never developed a thriving ecosystem like Apple's App Store or Android's Google Play.[89][91] Rival manufacturers have been forced to spend more on software and development costs in order to catch up to the iPhone. The iPhone's success has led to a decline in sales of high-end fashion phones and business-oriented smartphones such as Vertu and BlackBerry, respectively.[89][92]
Hardware

Screen and input
The touchscreen on the first five generations is a 9 cm (3.5 in) liquid crystal display with scratch-resistant glass, while the one on the iPhone 5 is 4 inches.[7] The capacitive touchscreen is designed for a bare finger, or multiple fingers for multi-touch sensing. The screens on the first three generations have a resolution of 320×480 (HVGA) at 163 ppi; those on the iPhone 4 and iPhone 4S have a resolution of 640×960 at 326 ppi, and the iPhone 5, 640×1136 at 326 ppi. The iPhone 5 model's screen results in an aspect ratio of nearly exactly 16:9.
The touch and gesture features of the iPhone are based on technology originally developed by FingerWorks.[93] Most gloves and styli prevent the necessary electrical conductivity;[94][95][96][97] although capacitive styli can be used with iPhone's finger-touch screen. The iPhone 3GS and later also feature a fingerprint-resistant oleophobic coating.[98]


The top and side of an iPhone 3GS, externally identical to the iPhone 3G. From left to right, sides: wake/sleep button, SIM card slot, headphone jack, silence switch, volume controls. The switches were black plastic on the first generation iPhone. Top: earpiece, screen.
The iPhone has a minimal hardware user interface, featuring five buttons. The only physical menu button is situated directly below the display, and is called the "Home button" because it closes the active app and navigates to the home screen of the interface. The home button is denoted not by a house, as on many other similar devices, but a rounded square, reminiscent of the shape of icons on the home screen.
A multifunction sleep/wake button is located on the top of the device. It serves as the unit's power button, and also controls phone calls. When a call is received, pressing the sleep/wake button once silences the ringtone, and when pressed twice transfers the call to voicemail. Situated on the left spine are the volume adjustment controls. The iPhone 4 has two separate circular buttons to increase and decrease the volume; all earlier models house two switches under a single plastic panel, known as a rocker switch, which could reasonably be counted as either one or two buttons.
Directly above the volume controls is a ring/silent switch that when engaged mutes telephone ringing, alert sounds from new & sent emails, text messages, and other push notifications, camera shutter sounds, Voice Memo sound effects, phone lock/unlock sounds, keyboard clicks, and spoken autocorrections. This switch does not mute alarm sounds from the Clock application, and in some countries or regions it will not mute the camera shutter or Voice Memo sound effects.[99] All buttons except Home were made of plastic on the original first generation iPhone and metal on all later models. The touchscreen furnishes the remainder of the user interface.
A software update in January 2008[100] allowed the first-generation iPhone to use cell tower and Wi-Fi network locations trilateration,[101] despite lacking GPS hardware. Since the iPhone 3G generation, the smartphone employ A-GPS operated by the United States. Since the iPhone 4S generation the device also supports the GLONASS global positioning system, which is operated by Russia.
Sensors
The display responds to three sensors (four since the iPhone 4). Moving the iPhone around triggers two other sensors (three since the iPhone 4), which are used to enable motion-controlled gaming applications and location-based services.
Proximity sensor
A proximity sensor deactivates the display and touchscreen when the device is brought near the face during a call. This is done to save battery power and to prevent inadvertent inputs from the user's face and ears.
Ambient light sensor
An ambient light sensor adjusts the display brightness which in turn saves battery power.
Accelerometer
A 3-axis accelerometer senses the orientation of the phone and changes the screen accordingly, allowing the user to easily switch between portrait and landscape mode.[102] Photo browsing, web browsing, and music playing support both upright and left or right widescreen orientations.[103] Unlike the iPad, the iPhone does not rotate the screen when turned upside-down, with the Home button above the screen, unless the running program has been specifically designed to do so. The 3.0 update added landscape support for still other applications, such as email, and introduced shaking the unit as a form of input.[104][105] The accelerometer can also be used to control third-party apps, notably games.
Magnetometer
A magnetometer is built-in since the iPhone 3GS generation, which is used to measure the strength and/or direction of the magnetic field in the vicinity of the device. Sometimes certain devices or radio signals can interfere with the magnetometer requiring users to either move away from the interference or re-calibrate by moving the device in a figure 8 motion. Since the iPhone 3GS, the iPhone also features a Compass app which was unique at time of release, showing a compass that points in the direction of the magnetic field.
Gyroscopic sensor
Beginning with the iPhone 4 generation, Apple's smartphones also include a gyroscopic sensor, enhancing its perception of how it is moved.
Audio and output


One of two speakers (left) and the microphone (right) surround the dock connector on the base of the 1st-generation iPhone. If a headset is plugged in, sound is played through it instead.
On the bottom of the iPhone, there is a speaker to the left of the dock connector and a microphone to the right. There is an additional loudspeaker above the screen that serves as an earpiece during phone calls. The iPhone 4 includes an additional microphone at the top of the unit for noise cancellation, and switches the placement of the microphone and speaker on the base on the unit—the speaker is on the right.[106] Volume controls are located on the left side of all iPhone models and as a slider in the iPod application.
The 3.5mm TRRS connector for the headphones is located on the top left corner of the device for the first five generations (original through 4S), after which time it was moved to the bottom left corner.[107] The headphone socket on the 1st-generation iPhone is recessed into the casing, making it incompatible with most headsets without the use of an adapter.[108] Subsequent generations eliminated the problem by using a flush-mounted headphone socket. Cars equipped with an auxiliary jack allow handsfree use of the iPhone while driving as a substitute for Bluetooth.
Apple's own headset has a multipurpose button near the microphone that can play or pause music, skip tracks, and answer or end phone calls without touching the iPhone. A small number of third-party headsets specifically designed for the iPhone also include the microphone and control button.[109] The current headsets also provide volume controls, which are only compatible with more recent models.[110] A fourth ring in the audio jack carries this extra information.
The built-in Bluetooth 2.x+EDR supports wireless earpieces and headphones, which requires the HSP profile. Stereo audio was added in the 3.0 update for hardware that supports A2DP.[104][105] While non-sanctioned third-party solutions exist, the iPhone does not officially support the OBEX file transfer protocol.[111] The lack of these profiles prevents iPhone users from exchanging multimedia files, such as pictures, music and videos, with other Bluetooth-enabled cell phones.
Composite[112] or component[113] video at up to 576i and stereo audio can be output from the dock connector using an adapter sold by Apple. iPhone 4 also supports 1024×768 VGA output[114] without audio, and HDMI output,[115] with stereo audio, via dock adapters. The iPhone did not support voice recording until the 3.0 software update.[104][105]
Battery


Replacing the battery requires disassembling the iPhone unit and exposing the internal hardware
The iPhone features an internal rechargeable lithium-ion battery. Like an iPod, but unlike most other mobile phones, the battery is not user-replaceable.[108][116] The iPhone can be charged when connected to a computer for syncing across the included USB to dock connector cable, similar to charging an iPod. Alternatively, a USB to AC adapter (or "wall charger," also included) can be connected to the cable to charge directly from an AC outlet.
Apple runs tests on preproduction units to determine battery life. Apple's website says that the battery life "is designed to retain up to 80% of its original capacity after 400 full charge and discharge cycles",[117] which is comparable to iPod batteries.
The battery life of early models of the iPhone has been criticized by several technology journalists as insufficient and less than Apple's claims.[118][119][120][121] This is also reflected by a J. D. Power and Associates customer satisfaction survey, which gave the "battery aspects" of the iPhone 3G its lowest rating of 2 out of 5 stars.[122][123]
If the battery malfunctions or dies prematurely, the phone can be returned to Apple and replaced for free while still under warranty.[124] The warranty lasts one year from purchase and can be extended to two years with AppleCare. The battery replacement service and its pricing was not made known to buyers until the day the product was launched;[125][126] it is similar to how Apple (and third parties) replace batteries for iPods. The Foundation for Taxpayer and Consumer Rights, a consumer advocate group, has sent a complaint to Apple and AT&T over the fee that consumers have to pay to have the battery replaced.[125]
Since July 2007, third-party battery replacement kits have been available[127] at a much lower price than Apple's own battery replacement program. These kits often include a small screwdriver and an instruction leaflet, but as with many newer iPod models the battery in the first generation iPhone has been soldered in. Therefore a soldering iron is required to install the new battery. The iPhone 3G uses a different battery fitted with a connector that is easier to replace.[128]
A patent filed by the corporation, published in late July 2013, revealed the development of a new iPhone battery system that uses location data in combination with data on the user's habits to moderate the handsets power settings accordingly. Apple is working towards a power management system that will provide features such as the ability of the iPhone to estimate the length of time a user will be away from a power source to modify energy usage and a detection function that adjusts the charging rate to best suit the type of power source that is being used.[129]


The iPhone 4 is the first generation to have two cameras. The LED flash for the rear-facing camera (top) and the forward-facing camera (bottom) are available on the iPhone 4 and subsequent models.
Camera
The 1st-generation iPhone and iPhone 3G have a fixed-focus 2.0-megapixel camera on the back for digital photos. It has no optical zoom, flash or autofocus, and does not natively support video recording. (iPhone 3G can record video via a third-party app available on the App Store, and jailbreaking also allows users to do so.) iPhone OS 2.0 introduced geotagging for photos.
The iPhone 3GS has a 3.2-megapixel camera with autofocus, auto white balance, and auto macro (up to 10 cm). Manufactured by OmniVision, the camera can also capture 640×480 (VGA resolution) video at 30 frames per second,[130] although unlike higher-end CCD-based video cameras, it exhibits the rolling shutter effect.[131] The video can be cropped on the iPhone and directly uploaded to YouTube, MobileMe, or other services.
The iPhone 4 introduced a 5.0-megapixel camera (2592×1936 pixels) that can record video at 720p resolution, considered high-definition. It also has a backside-illuminated sensor that can capture pictures in low light and an LED flash that can stay lit while recording video.[132] It is the first iPhone that can natively do high dynamic range photography.[133] The iPhone 4 also has a second camera on the front that can take VGA photos and record SD video. Saved recordings may be synced to the host computer, attached to email, or (where supported) sent by MMS.
The iPhone 4S' camera can shoot 8-MP stills and 1080p video, can be accessed directly from the lock screen, and can be triggered using the volume-up button as a shutter trigger. The built-in gyroscope can stabilize the image while recording video.
The iPhone 5 and iPhone 4S, running iOS 6 or later, can take panoramas using the built-in camera app,[134] and the iPhone 5 also can take still photos while recording video.[135]
The camera on the iPhone 5 reportedly shows purple haze when the light source is just out of frame,[136] although Consumer Reports said it "is no more prone to purple hazing on photos shot into a bright light source than its predecessor or than several Android phones with fine cameras..."[137]
On all five model generations, the phone can be configured to bring up the camera app by quickly pressing the home key twice.[138] On all iPhones running iOS 5, it can also be accessed from the lock screen directly.
Beta code found in iOS 7 indicates that Apple may be outfitting the camera of the next iPhone with a slow-motion mode.[139]
Storage and SIM


An iPhone 3G with the SIM slot open. The SIM ejector tool is still placed in the eject hole.
The iPhone was initially released with two options for internal storage size: 4 GB or 8 GB. On September 5, 2007, Apple discontinued the 4 GB models.[140] On February 5, 2008, Apple added a 16 GB model.[141] The iPhone 3G was available in 16 GB and 8 GB. The iPhone 3GS came in 16 GB and 32 GB variants and remained available in 8 GB until September 2012, more than three years after its launch.
The iPhone 4 is available in 16 GB and 32 GB variants, as well as an 8 GB variant to be sold alongside the iPhone 4S at a reduced price point. The iPhone 4S is available in three sizes: 16 GB, 32 GB and 64 GB. All data is stored on the internal flash drive; the iPhone does not support expanded storage through a memory card slot, or the SIM card. The iPhone 5 is available in the same three sizes previously available to the iPhone 4S: 16 GB, 32 GB, and 64 GB.
GSM models of the iPhone use a SIM card to identify themselves to the GSM network. The SIM sits in a tray, which is inserted into a slot at the top of the device. The SIM tray can be ejected with a paper clip or the "SIM ejector tool" (a simple piece of die-cut sheet metal) included with the iPhone 3G and 3GS in the United States and with all models elsewhere in the world.[142][143] Some iPhone models shipped with a SIM ejector tool which was fabricated from an alloy dubbed "Liquidmetal".[144] In most countries, the iPhone is usually sold with a SIM lock, which prevents the iPhone from being used on a different mobile network.[145]
The GSM iPhone 4 features a MicroSIM card that is located in a slot on the right side of the device.[146]
The CDMA model of the iPhone 4, just the same as any other CDMA-only cell phone, does not use a SIM card or have a SIM card slot.
An iPhone 4S activated on a CDMA carrier, however, does have a SIM card slot but does not rely on a SIM card for activation on that CDMA network. A CDMA-activated iPhone 4S usually has a carrier-approved roaming SIM preloaded in its SIM slot at the time of purchase that is used for roaming on certain carrier-approved international GSM networks only. The SIM slot is locked to only use the roaming SIM card provided by the CDMA carrier.[147]
In the case of Verizon, for example, one can request that the SIM slot be unlocked for international use by calling their support number and requesting an international unlock if their account has been in good standing for the past 60 days.[148] This method only unlocks the iPhone 4S for use on international carriers. An iPhone 4S that has been unlocked in this way will reject any non international SIM cards (AT&T Mobility or T-Mobile USA, for example).
The iPhone 5 uses the nano-SIM, in order to save more space for internal components.
Liquid contact indicators
All iPhones (and many other devices by Apple) have a small disc at the bottom of the headphone jack that changes from white to red on contact with water; the iPhone 3G and later models also have a similar indicator at the bottom of the dock connector.[149] Because Apple warranties do not cover water damage, employees examine the indicators before approving warranty repair or replacement.
The iPhone's indicators are more exposed than those in some mobile phones from other manufacturers, which carry them in a more protected location, such as beneath the battery behind a battery cover. The iPhone's can be triggered during routine use, by an owner's sweat,[150] steam in a bathroom, and other light environmental moisture.[151] Criticism led Apple to change its water damage policy for iPhones and similar products, allowing customers to request further internal inspection of the phone to verify if internal liquid damage sensors were triggered.[152]
Included items

All iPhone models include written documentation, and a dock connector to USB cable. The first generation and 3G iPhones also came with a cleaning cloth. The first generation iPhone included a stereo headset (earbuds and a microphone) and a plastic dock to hold the unit upright while charging and syncing. The iPhone 3G includes a similar headset plus a SIM eject tool (the first generation model requires a paperclip). The iPhone 3GS includes the SIM eject tool and a revised headset, which adds volume buttons (not functional with previous iPhone versions).[110][153]
The iPhone 3G and 3GS are compatible with the same dock, sold separately, but not the first generation model's dock.[154] All versions include a USB power adapter, or "wall charger," which allows the iPhone to charge from an AC outlet. The iPhone 3G and iPhone 3GS sold in North America, Japan, Colombia, Ecuador, or Peru[155][156] include an ultracompact USB power adapter.
Software

Main articles: iOS and iOS version history


The iPhone Home screen of iOS 7 shows most of the applications provided by Apple. Users can download additional applications from the App store, create Web Clips, rearrange the icons, and create and delete folders.
The iPhone, iPod Touch and iPad run an operating system known as iOS (formerly iPhone OS). It is a variant of the same Darwin operating system core that is found in Mac OS X. Also included is the "Core Animation" software component from Mac OS X v10.5 Leopard. Together with the PowerVR hardware (and on the iPhone 3GS, OpenGL ES 2.0), it is responsible for the interface's motion graphics. The operating system takes up less than half a gigabyte.[157]
It is capable of supporting bundled and future applications from Apple, as well as from third-party developers. Software applications cannot be copied directly from Mac OS X but must be written and compiled specifically for iOS.
Like the iPod, the iPhone is managed from a computer using iTunes. The earliest versions of the OS required version 7.3 or later, which is compatible with Mac OS X version 10.3.9 Panther or later, and 32-bit Windows XP or Vista.[158] The release of iTunes 7.6 expanded this support to include 64-bit versions of XP and Vista,[159] and a workaround has been discovered for previous 64-bit Windows operating systems.[160]
Apple provides free updates to the OS for the iPhone through iTunes,[157] and major updates have historically accompanied new models.[161] Such updates often require a newer version of iTunes—for example, the 3.0 update requires iTunes 8.2—but the iTunes system requirements have stayed the same. Updates include bug fixes, security patches and new features.[162] For example, iPhone 3G users initially experienced dropped calls until an update was issued.[163][164]
Version 3.1 required iTunes 9.0, and iOS 4 required iTunes 9.2. iTunes 10.5, which is required to sync and activate iOS 5, requires Mac OS X 10.5.8 or Leopard on G4 or G5 computers on 800 MHz or higher; versions 10.3 and 10.4 and 10.5–10.5.7 are no longer supported.
Interface
The interface is based around the home screen, a graphical list of available applications. iPhone applications normally run one at a time. Starting with the iPhone 4, a primitive version of multitasking came into play. Users could double click the home button to select recently opened.[165] However, the apps never ran in the background. Starting with iOS 7, though, apps can truly multitask, and each open application runs in the background when not.[166] S although most functionality is still available when making a call or listening to music. The home screen can be accessed at any time by a hardware button below the screen, closing the open application in the process.[167]
By default, the Home screen contains the following icons: Messages (SMS and MMS messaging), Calendar, Photos, Camera, YouTube, Stocks, Maps (Google Maps), Weather, Voice Memos, Notes, Clock, Calculator, Settings, iTunes (store), App Store, (on the iPhone 3GS and iPhone 4) Compass, FaceTime and GameCenter were added in iOS 4.0 and 4.1 respectively. In iOS 5, Reminders and Newsstand were added, as well as the iPod application split into separate Music and Videos applications. iOS 6 added Passbook as well as an updated version of Maps that relies on data provided by TomTom as well as other sources. iOS 6 also added a Clock application onto the iPad's homescreen. However, it also no longer support YouTube. Docked at the base of the screen, four icons for Phone, Mail, Safari (Internet), and Music delineate the iPhone's main purposes.[168] On January 15, 2008, Apple released software update 1.1.3, allowing users to create "Web Clips", home screen icons that resemble apps that open a user-defined page in Safari. After the update, iPhone users can rearrange and place icons on up to nine other adjacent home screens, accessed by a horizontal swipe.[100]
Users can also add and delete icons from the dock, which is the same on every home screen. Each home screen holds up to twenty icons for iPhone 2G, 3G, 4 and 4S, while each home screen for iPhone 5 will hold up to twenty-four icons due to a larger screen display, and the dock holds up to four icons. Users can delete Web Clips and third-party applications at any time, and may select only certain applications for transfer from iTunes. Apple's default programs, however, may not be removed. The 3.0 update adds a system-wide search, known as Spotlight, to the left of the first home screen.[104][105]
Almost all input is given through the touch screen, which understands complex gestures using multi-touch. The iPhone's interaction techniques enable the user to move the content up or down by a touch-drag motion of the finger. For example, zooming in and out of web pages and photos is done by placing two fingers on the screen and spreading them farther apart or bringing them closer together, a gesture known as "pinching".
Scrolling through a long list or menu is achieved by sliding a finger over the display from bottom to top, or vice versa to go back. In either case, the list moves as if it is pasted on the outer surface of a wheel, slowly decelerating as if affected by friction. In this way, the interface simulates the physics of a real object.
Other user-centered interactive effects include horizontally sliding sub-selection, the vertically sliding keyboard and bookmarks menu, and widgets that turn around to allow settings to be configured on the other side. Menu bars are found at the top and bottom of the screen when necessary. Their options vary by program, but always follow a consistent style motif. In menu hierarchies, a "back" button in the top-left corner of the screen displays the name of the parent folder.
Phone


When making a call, the iPhone presents a number of options; including FaceTime on supported models. The screen is automatically disabled when held close to the face.
The iPhone allows audio conferencing, call holding, call merging, caller ID, and integration with other cellular network features and iPhone functions. For example, if music is playing when a call is received, the music fades out, and fades back in when the call has ended.
The proximity sensor shuts off the screen and touch-sensitive circuitry when the iPhone is brought close to the face, both to save battery and prevent unintentional touches. The iPhone does not support video calling or videoconferencing on versions prior to the fourth generation, as there is only one camera on the opposite side of the screen.[169]
The iPhone 4 supports video calling using either the front or back camera over Wi-Fi, a feature Apple calls FaceTime.[170] The first two models only support voice dialing through third-party applications.[171] Voice control, available only on the iPhone 3GS and iPhone 4, allows users to say a contact's name or number and the iPhone will dial.[172]
The iPhone includes a visual voicemail (in some countries)[173] feature allowing users to view a list of current voicemail messages on-screen without having to call into their voicemail. Unlike most other systems, messages can be listened to and deleted in a non-chronological order by choosing any message from an on-screen list.
A music ringtone feature was introduced in the United States on September 5, 2007. Users can create custom ringtones from songs purchased from the iTunes Store for a small additional fee. The ringtones can be 3 to 30 seconds long from any part of a song, can fade in and out, pause from half a second to five seconds when looped, or loop continuously. All customizing can be done in iTunes,[174] or alternatively with Apple's GarageBand software 4.1.1 or later (available only on Mac OS X)[175] or third-party tools.[176]
With the release of iOS 6, which was released on September 19, 2012, Apple added features that enable the user to have options to decline a phone call when a person is calling them. The user has the capability to reply with a message, or to set a reminder to call them back at a later time.[177]
On September 12, 2012, Apple unveiled the iPhone 5, the sixth iteration of the iPhone. New features included a bigger 4-inch screen, thinner design and 4G LTE.
Multimedia
The layout of the music library is similar to that of an iPod or current Symbian S60 phones. The iPhone can sort its media library by songs, artists, albums, videos, playlists, genres, composers, podcasts, audiobooks, and compilations. Options are always presented alphabetically, except in playlists, which retain their order from iTunes. The iPhone uses a large font that allows users plenty of room to touch their selection.
Users can rotate their device horizontally to landscape mode to access Cover Flow. Like on iTunes, this feature shows the different album covers in a scroll-through photo library. Scrolling is achieved by swiping a finger across the screen. Alternatively, headset controls can be used to pause, play, skip, and repeat tracks. On the iPhone 3GS, the volume can be changed with the included Apple Earphones, and the Voice Control feature can be used to identify a track, play songs in a playlist or by a specific artist, or create a Genius playlist.[172]
The iPhone supports gapless playback.[178] Like the fifth-generation iPods introduced in 2005, the iPhone can play digital video, allowing users to watch TV shows and movies in widescreen. Double-tapping switches between widescreen and fullscreen video playback.
The iPhone allows users to purchase and download songs from the iTunes Store directly to their iPhone. The feature originally required a Wi-Fi network, but now since 2012 can use the cellular data network if one is not available.[179]
The iPhone includes software that allows the user to upload, view, and email photos taken with the camera. The user zooms in and out of photos by sliding two fingers further apart or closer together, much like Safari. The Camera application also lets users view the camera roll, the pictures that have been taken with the iPhone's camera. Those pictures are also available in the Photos application, along with any transferred from iPhoto or Aperture on a Mac, or Photoshop on a Windows PC.
Internet connectivity


Wikipedia Main Page on the iPhone Safari web browser in landscape mode
Internet access is available when the iPhone is connected to a local area Wi-Fi or a wide area GSM or EDGE network, both second-generation (2G) wireless data standards. The iPhone 3G introduced support for third-generation UMTS and HSDPA 3.6,[180] only the iPhone 4S supports HSUPA networks (14.4 Mbit/s), and only the iPhone 3GS and iPhone 4 support HSDPA 7.2.[181]
AT&T introduced 3G in July 2004,[182] but as late as 2007, Steve Jobs stated that it was still not widespread enough in the US, and the chipsets not energy efficient enough, to be included in the iPhone.[95][183] Support for 802.1X, an authentication system commonly used by university and corporate Wi-Fi networks, was added in the 2.0 version update.[184]
By default, the iPhone will ask to join newly discovered Wi-Fi networks and prompt for the password when required. Alternatively, it can join closed Wi-Fi networks manually.[185] The iPhone will automatically choose the strongest network, connecting to Wi-Fi instead of EDGE when it is available.[186] Similarly, the iPhone 3G, 3GS and 4 prefer 3G to 2G, and Wi-Fi to either.[187]
Wi-Fi, Bluetooth, and 3G (on the iPhone 3G onwards) can all be deactivated individually. Airplane mode disables all wireless connections at once, overriding other preferences. However, once in Airplane mode, one can explicitly enable Wi-Fi and/or Bluetooth modes to join and continue to operate over one or both of those networks while the cellular network transceivers remain off.
The iPhone 3GS has a maximum download rate of 7.2 Mbit/s.[188] Furthermore, email attachments as well as apps and media from Apple's various stores must be smaller than 20 MB to be downloaded over a cellular network.[189] Larger files, often email attachments or podcasts, must be downloaded over Wi-Fi (which has no file size limits). If Wi-Fi is unavailable, one workaround is to open the files directly in Safari.[190]
Safari is the iPhone's native web browser, and it displays pages similar to its Mac and Windows counterparts. Web pages may be viewed in portrait or landscape mode and the device supports automatic zooming by pinching together or spreading apart fingertips on the screen, or by double-tapping text or images.[191][192] It is worth mentioning that Safari doesn't allow file downloads except for predefined extensions. The iPhone does not support Flash.[193]
Consequently, the UK's Advertising Standards Authority adjudicated that an advertisement claiming the iPhone could access "all parts of the internet" should be withdrawn in its current form, on grounds of false advertising.[194] In a rare public letter in April 2010, Apple CEO Steve Jobs outlined the reasoning behind the absence of Flash on the iPhone (and iPad).[195] The iPhone supports SVG, CSS, HTML Canvas, and Bonjour.[196][197]
Google Chrome was introduced to the iOS on June 26, 2012. In a review by Chitika on July 18, 2012, they announced that the Google Chrome web browser has 1.5% of the iOS web browser market since its release.[198]
The maps application can access Google Maps in map, satellite, or hybrid form. It can also generate directions between two locations, while providing optional real-time traffic information. During the iPhone's announcement, Jobs demonstrated this feature by searching for nearby Starbucks locations and then placing a prank call to one with a single tap.[199][200] Support for walking directions, public transit, and street view was added in the version 2.2 software update, but no voice-guided navigation.[201]
The iPhone 3GS and iPhone 4 can orient the map with its digital compass.[202] Apple also developed a separate application to view YouTube videos on the iPhone, which streams videos after encoding them using the H.264 codec. Simple weather and stock quotes applications also tap into the Internet.
iPhone users can and do access the Internet frequently, and in a variety of places. According to Google, in 2008, the iPhone generated 50 times more search requests than any other mobile handset.[203] According to Deutsche Telekom CEO René Obermann, "The average Internet usage for an iPhone customer is more than 100 megabytes. This is 30 times the use for our average contract-based consumer customers."[204] Nielsen found that 98% of iPhone users use data services, and 88% use the internet.[39] In China, the iPhone 3G and iPhone 3GS were built and distributed without Wi-Fi.[205]
With the introduction of the Verizon iPhone in January 2011, the issue of using internet while on the phone has been brought to the public's attention. Under the two US carriers, internet and phone could be used simultaneously on AT&T networks, whereas Verizon networks only support the use of each separately.[206]
Text input


The virtual keyboard on the iPhone (first gen) touchscreen
For text input, the iPhone implements a virtual keyboard on the touchscreen. It has automatic spell checking and correction, predictive word capabilities, and a dynamic dictionary that learns new words. The keyboard can predict what word the user is typing and complete it, and correct for the accidental pressing of keys near the presumed desired key.[207]
The keys are somewhat larger and spaced farther apart when in landscape mode, which is supported by only a limited number of applications. Touching a section of text for a brief time brings up a magnifying glass, allowing users to place the cursor in the middle of existing text. The virtual keyboard can accommodate 21 languages, including character recognition for Chinese.[208]
Alternate characters with accents (for example, letters from the alphabets of other languages) can be typed from the keyboard by pressing the letter for 2 seconds and selecting the alternate character from the popup.[209] The 3.0 update brought support for cut, copy, or pasting text, as well as landscape keyboards in more applications.[104][105] On iPhone 4S, Siri allows dictation.
Email and text messages
The iPhone also features an email program that supports HTML email, which enables the user to embed photos in an email message. PDF, Word, Excel, and PowerPoint attachments to mail messages can be viewed on the phone.[210] Apple's MobileMe platform offers push email, which emulates the functionality of the popular BlackBerry email solution, for an annual subscription. Yahoo! offers a free push-email service for the iPhone. IMAP (although not Push-IMAP) and POP3 mail standards are also supported, including Microsoft Exchange[211] and Kerio Connect.[212]
In the first versions of the iPhone firmware, this was accomplished by opening up IMAP on the Exchange server. Apple has also licensed Microsoft ActiveSync and now[when?] supports the platform (including push email) with the release of iPhone 2.0 firmware.[213][214] The iPhone will sync email account settings over from Apple's own Mail application, Microsoft Outlook, and Microsoft Entourage, or it can be manually configured on the device itself. With the correct settings, the email program can access almost any IMAP or POP3 account.[215]
Text messages are presented chronologically in a mailbox format similar to Mail, which places all text from recipients together with replies. Text messages are displayed in speech bubbles (similar to iChat) under each recipient's name. The iPhone has built-in support for email message forwarding, drafts, and direct internal camera-to-email picture sending. Support for multi-recipient SMS was added in the 1.1.3 software update.[216] Support for MMS was added in the 3.0 update, but not for the original first generation iPhone[104][105] and not in the US until September 25, 2009.[217][218]
Third-party applications
See also: iOS SDK and App Store
At WWDC 2007 on June 11, 2007, Apple announced that the iPhone would support third-party web applications using Ajax that share the look and feel of the iPhone interface.[219] On October 17, 2007, Steve Jobs, in an open letter posted to Apple's "Hot News" weblog, announced that a software development kit (SDK) would be made available to third-party developers in February 2008. The iPhone SDK was officially announced and released on March 6, 2008, at the Apple Town Hall facility.[220]
It is a free download, with an Apple registration, that allows developers to develop native applications for the iPhone and iPod Touch, then test them in an "iPhone simulator". However, loading an application onto a real device is only possible after paying an Apple Developer Connection membership fee. Developers are free to set any price for their applications to be distributed through the App Store, of which they will receive a 70% share.[221]
Developers can also opt to release the application for free and will not pay any costs to release or distribute the application beyond the membership fee. The App Store was launched with the release of iOS 2.0, on July 11, 2008.[214] The update was free for iPhone users; owners of older iPod Touches were required to pay US$10 for it.[222]
Once a developer has submitted an application to the App Store, Apple holds firm control over its distribution. Apple can halt the distribution of applications it deems inappropriate, for example, I Am Rich, a US$1000 program that simply demonstrated the wealth of its user.[223] Apple has been criticized for banning third-party applications that enable a functionality that Apple does not want the iPhone to have: In 2008, Apple rejected Podcaster, which allowed iPhone users to download podcasts directly to the iPhone claiming it duplicated the functionality of iTunes.[224] Apple has since released a software update that grants this capability.[201]
NetShare, another rejected app, would have enabled users to tether their iPhone to a laptop or desktop, using its cellular network to load data for the computer.[225] Many carriers of the iPhone later globally allowed tethering before Apple officially supported it with the upgrade to the iOS 3.0, with AT&T Mobility being a relative latecomer in the United States.[226] In most cases, the carrier charges extra for tethering an iPhone.
Before the SDK was released, third-parties were permitted to design "Web Apps" that would run through Safari.[227] Unsigned native applications are also available for "jailbroken" phones.[228] The ability to install native applications onto the iPhone outside of the App Store is not supported by Apple, the stated reason being that such native applications could be broken by any software update, but Apple has stated it will not design software updates specifically to break native applications other than those that perform SIM unlocking.[229]
As of October 2013, Apple has passed 60 billion app downloads.[230]
Accessibility
The iPhone can enlarge text to make it more accessible for vision-impaired users,[231] and can accommodate hearing-impaired users with closed captioning and external TTY devices.[232] The iPhone 3GS also features white on black mode, VoiceOver (a screen reader), and zooming for impaired vision, and mono audio for limited hearing in one ear.[233] Apple regularly publishes Voluntary Product Accessibility Templates which explicitly state compliance with the US regulation "Section 508".[234]
Vulnerability
See also: Mobile security
In 2007, 2010, and 2011, developers released a series of tools called JailbreakMe that used security vulnerabilities in Mobile Safari rendering in order to jailbreak the device (which allows users to install any compatible software on the device instead of only App Store apps).[235][236][237] These exploits were each soon fixed by iOS updates from Apple. Theoretically these flaws could have also been used for malicious purposes.[238]
In July 2011, Apple released iOS 4.3.5 (4.2.10 for CDMA iPhone) to fix a security vulnerability with certificate validation.
The American and British intelligence agencies, the National Security Agency (NSA) and the Government Communications Headquarters (GCHQ) respectively, have access to the user data in iPhones. They are able to read almost all information on the phone, including SMS, location, emails, and notes.[239]
Following the release of the iPhone 5s model, a group of German hackers called the Chaos Computer Club announced on September 21, 2013 that they had bypassed Apple's new Touch ID fingerprint sensor by using "easy everyday means." The group explained that the security system had been defeated by photographing a fingerprint from a glass surface and using that captured image as verification. The spokesman for the group stated: "We hope that this finally puts to rest the illusions people have about fingerprint biometrics. It is plain stupid to use something that you can't change and that you leave everywhere every day as a security token."[240][241]

Intellectual property

Apple has filed more than 200 patent applications related to the technology behind the iPhone.[283][284]
LG Electronics claimed the design of the iPhone was copied from the LG Prada. Woo-Young Kwak, head of LG Mobile Handset R&D Center, said at a press conference: "we consider that Apple copied Prada phone after the design was unveiled when it was presented in the iF Design Award and won the prize in September 2006."[285]
On September 3, 1993, Infogear filed for the US trademark "I PHONE"[286] and on March 20, 1996, applied for the trademark "IPhone".[287] "I Phone" was registered in March 1998,[286] and "IPhone" was registered in 1999.[287] Since then, the I PHONE mark had been abandoned.[286] Infogear trademarks cover "communications terminals comprising computer hardware and software providing integrated telephone, data communications and personal computer functions" (1993 filing),[286] and "computer hardware and software for providing integrated telephone communication with computerized global information networks" (1996 filing).[288]
Infogear released a telephone with an integrated web browser under the name iPhone in 1998.[289] In 2000, Infogear won an infringement claim against the owners of the iphones.com domain name.[290] In June 2000, Cisco Systems acquired Infogear, including the iPhone trademark.[291] On December 18, 2006, they released a range of re-branded Voice over IP (VoIP) sets under the name iPhone.[292]
In October 2002, Apple applied for the "iPhone" trademark in the United Kingdom, Australia, Singapore, and the European Union. A Canadian application followed in October 2004, and a New Zealand application in September 2006. As of October 2006, only the Singapore and Australian applications had been granted. In September 2006, a company called Ocean Telecom Services applied for an "iPhone" trademark in the United States, United Kingdom and Hong Kong, following a filing in Trinidad and Tobago.[293]
As the Ocean Telecom trademark applications use exactly the same wording as the New Zealand application of Apple, it is assumed that Ocean Telecom is applying on behalf of Apple.[294] The Canadian application was opposed in August 2005, by a Canadian company called Comwave who themselves applied for the trademark three months later. Comwave has been selling VoIP devices called iPhone since 2004.[291]
Shortly after Steve Jobs' January 9, 2007, announcement that Apple would be selling a product called iPhone in June 2007, Cisco issued a statement that it had been negotiating trademark licensing with Apple and expected Apple to agree to the final documents that had been submitted the night before.[295] On January 10, 2007, Cisco announced it had filed a lawsuit against Apple over the infringement of the trademark iPhone, seeking an injunction in federal court to prohibit Apple from using the name.[296] More recently,[when?] Cisco claimed that the trademark lawsuit was a "minor skirmish" that was not about money, but about interoperability.[297]
On February 2, 2007, Apple and Cisco announced that they had agreed to temporarily suspend litigation while they held settlement talks,[298] and subsequently announced on February 20, 2007, that they had reached an agreement. Both companies will be allowed to use the "iPhone" name[299] in exchange for "exploring interoperability" between their security, consumer, and business communications products.[300]
The iPhone has also inspired several leading high-tech clones,[301] driving both the popularity of Apple and consumer willingness to upgrade iPhones quickly.[302]
On October 22, 2009, Nokia filed a lawsuit against Apple for infringement of its GSM, UMTS and WLAN patents. Nokia alleges that Apple has been violating ten of the patents of Nokia since the iPhone initial release.[303]
In December 2010, Reuters reported that some iPhone and iPad users were suing Apple Inc. because some applications were passing user information to third-party advertisers without permission. Some makers of the applications such as Textplus4, Paper Toss, The Weather Channel, Dictionary.com, Talking Tom Cat and Pumpkin Maker have also been named as co-defendants in the lawsuit.[304]
In August 2012, Apple won a smartphone patent lawsuit in the USA against Samsung, the world's largest maker of smartphones.[305]
In March 2013, an Apple patent for a wraparound display was revealed.[306]
Secret tracking

Since April 20, 2011, a hidden unencrypted file on the iPhone and other iOS devices has been widely discussed in the media.[307][308] It was alleged that the file, labeled "consolidated.db", constantly stores the iPhone user's movement by approximating geographic locations calculated by triangulating nearby cell phone towers, a technology proven to be inaccurate at times.[309] The file was released with the June 2010 update of Apple iOS4 and may contain almost one year's worth of data. Previous versions of iOS stored similar information in a file called "h-cells.plist".[310]
F-Secure discovered that the data is transmitted to Apple twice a day and postulate that Apple is using the information to construct their global location database similar to the ones constructed by Google and Skyhook through wardriving.[311] Nevertheless, unlike the Google "Latitude" application, which performs a similar task on Android phones, the file is not dependent upon signing a specific EULA or even the user's knowledge, but it is stated in the 15,200 word-long terms and conditions of the iPhone that "Apple and [their] partners and licensees may collect, use, and share precise location data, including the real-time geographic location of [the user's] Apple computer or device".[312]
The file is also automatically copied onto the user's computer once synchronized with the iPhone. An open source application named "iPhoneTracker", which turns the data stored in the file into a visual map, was made available to the public in April 2011.[313] While the file cannot be erased without jailbreaking the phone, it can be encrypted.[314]
Apple gave an official response on their web site on April 27,[315] 2011, after questions were submitted by users, the Associated Press and others.[316] Apple clarified that the data is a small portion of their crowd-sourced location database cache of Wi-Fi hotspots and cell towers which is downloaded from Apple into the iPhone for making location services faster than with only GPS, therefore the data does not represent the locations of the iPhone. The volume of data retained was an error. Apple issued an update for iOS (version 4.3.3, or 4.2.8 for the CDMA iPhone 4) which reduced the size of the cache, stopped it being backed up to iTunes, and erased it entirely whenever location services were turned off.[315] The upload to Apple can also be selectively disabled from "System services", "Cell Network Search."
Intelligence agency access

It was revealed as apart of the 2013 mass surveillance disclosures that the American and British intelligence agencies, the National Security Agency (NSA) and the Government Communications Headquarters (GCHQ) respectively, have access to the user data in iPhones, BlackBerrys, and Android phones. They are able to read almost all smartphone information, including SMS, location, emails, and notes.[239]

Apple tightly controls certain aspects of the iPhone. According to Jonathan Zittrain, the emergence of closed devices like the iPhone have made computing more proprietary than early versions of Microsoft Windows.[317]
The hacker community has found many workarounds, most of which are disallowed by Apple and make it difficult or impossible to obtain warranty service.[318] "Jailbreaking" allows users to install apps not available on the App Store or modify basic functionality. SIM unlocking allows the iPhone to be used on a different carrier's network.[319] However, in the United States, Apple cannot void an iPhone's warranty unless it can show that a problem or component failure is linked to the installation or placement of after-market item such as unauthorized applications, because of the Federal Trade Commission's Magnuson-Moss Warranty Act of 1975[320]
The iPhone also has an area and settings where parents can set restriction or parental controls[321] on apps that can be downloaded or used within the iPhone. The restrictions area will require a password.[322]
Activation
The iPhone normally prevents access to its media player and web features unless it has also been activated as a phone with an authorized carrier. On July 3, 2007, Jon Lech Johansen reported on his blog that he had successfully bypassed this requirement and unlocked the iPhone's other features with a combination of custom software and modification of the iTunes binary. He published the software and offsets for others to use.[323]
Unlike the first generation iPhone, the iPhone 3G must be activated in the store in most countries.[324] This makes the iPhone 3G more difficult, but not impossible, to hack. The need for in-store activation, as well as the huge number of first-generation iPhone and iPod Touch users upgrading to iPhone OS 2.0, caused a worldwide overload of Apple's servers on July 11, 2008, the day on which both the iPhone 3G and iPhone OS 2.0 updates as well as MobileMe were released. After the update, devices were required to connect to Apple's servers to authenticate the update, causing many devices to be temporarily unusable.[325]
Users on the O2 network in the United Kingdom, however, can buy the phone online and activate it via iTunes as with the previous model.[326] Even where not required, vendors usually offer activation for the buyer's convenience. In the US, Apple has begun to offer free shipping on both the iPhone 3G and the iPhone 3GS (when available), reversing the in-store activation requirement. Best Buy and Walmart will also sell the iPhone.[327]
Unapproved third-party software and jailbreaking

The iPhone's operating system is designed to only run software that has an Apple-approved cryptographic signature. This restriction can be overcome by "jailbreaking" the phone,[328] which involves replacing the iPhone's firmware with a slightly modified version that does not enforce the signature check. Doing so may be a circumvention of Apple's technical protection measures.[329] Apple, in a statement to the United States Copyright Office in response to Electronic Frontier Foundation (EFF) lobbying for a DMCA exception for this kind of hacking, claimed that jailbreaking the iPhone would be copyright infringement due to the necessary modification of system software.[330] However in 2010 Jailbreaking was declared officially legal in the United States by the DMCA.[331] Jailbroken iPhones may be susceptible to computer viruses, but few such incidents have been reported.[332][333]
iOS and Android 2.3.3 'Gingerbread' may be set up to dual boot on a jailbroken iPhone with the help of OpeniBoot or iDroid.[334][335]
SIM unlocking
United States

Most iPhones were and are still sold with a SIM lock, which restricts the use of the phone to one particular carrier, a common practice with subsidized GSM phones. Unlike most GSM phones however, the phone cannot be officially unlocked by entering a code.[336] The locked/unlocked state is maintained on Apple's servers per IMEI and is set when the iPhone is activated.
While the iPhone was initially sold in the US only on the AT&T network with a SIM lock in place, various hackers have found methods to "unlock" the phone from a specific network.[337] Although AT&T, Sprint and Verizon are the only authorized iPhone carriers in the United States, unlocked iPhones can be used with other carriers after unlocking.[338] For example, an unlocked iPhone may be used on the T-Mobile network in the US but, while an unlocked iPhone is compatible with T-Mobile's voice network, it may not be able to make use of 3G functionality (i.e., no mobile web or e-mail, etc.).[339][not in citation given] More than a quarter of the original 1st generation iPhones sold in the US were not registered with AT&T. Apple speculates that they were likely shipped overseas and unlocked, a lucrative market before the iPhone 3G's worldwide release.[38][340][341]
On March 26, 2009, AT&T in the United States began selling the iPhone without a contract, though still SIM-locked to their network.[342] The up-front purchase price of such iPhone units is often twice as expensive as those bundled with contracts.[343] Outside of the United States, policies differ, especially in US territories and insular areas like Guam, where GTA Teleguam is the exclusive carrier for the iPhone, since none of the three US carriers (AT&T, Sprint, and Verizon) has a presence in the area.[344]
Beginning April 8, 2012, AT&T began offering a factory SIM unlock option (which Apple calls a "whitelisting", allowing it to be used on any carrier the phone supports) for iPhone owners.[345]
It has been reported that the Verizon iPhone 5 comes factory unlocked. After such discovery, Verizon announced that the Verizon iPhone 5 would remain unlocked, due to the regulations that the FCC had placed on the 700 MHz C-Block spectrum, which is utilized by Verizon.[346]
United Kingdom
In the United Kingdom, networks O2, EE, 3, Vodafone, as well as MVNO Tesco Mobile sell the device under subsidised contracts, or for use on pay as you go. They are locked to the network initially, though are usually able to be unlocked either after a certain period of contract length has passed, or for a small fee. However, all current versions of iPhone are available for purchase SIM-free from the Apple Store or Apple's Online Store, consequently, they are unlocked for use on any GSM network too.[347]
Australia and other countries
Five major carriers in Australia, (Three, Optus, Telstra, Virgin Mobile, and Vodafone),[348] offer legitimate unlocking, now at no cost for all iPhone devices, both current and prior models. The iPhone 3GS and the iPhone 4 can also be bought unlocked from Apple Retail Stores or the Apple Online Store.[145]
Internationally, policies vary, but many carriers sell the iPhone unlocked for full retail price.[145]
Legal battle over brand name

Mexico
In 2003, four years before the iPhone was officially introduced, the trademark iFone was registered in Mexico by a communications systems and services company, iFone.[349] Apple tried to gain control over its brandname, but a Mexican court refused the request. The case began in 2009, when the Mexican firm sued Apple. The Supreme court of Mexico upheld that iFone is the rightful owner, and held that Apple iPhone is a trademark violation.[350]
Brazil
Also in Brazil the brand IPHONE has been registered in 2000 by the company then called Gradiente Eletrônica S.A., now IGB Eletrônica S.A. According to the filing, Gradiente foresaw the revolution in the convergence of voice and data over the Internet at the time.[351]
In Brazil, the final battle over the brandname was finished in 2008. In December 18, 2012, IGB launched its own line of Android smartphones under the tradename to which it has exclusive rights in the local market.[351] In February 2013, the Brazilian Patent and Trademark Office, (known as "Instituto Nacional Da Propriedade Industrial") issued a ruling that Gradiente Eletrônica, not Apple, owned the “iPhone” mark in Brazil. The “iPhone” term was registered by Gradiente in 2000, 7 years prior to Apple’s release of its iPhone. This decision came 3 months after Gradiente Eletrônica launched a lower-cost smartphone using the iPhone brandHERO DYD
