iPhone Technology

The iPhone is a line of smartphones designed and marketed by Apple Inc. The first iPhone was unveiled by Steve Jobs, then CEO of Apple, on January 9, 2007 and released on June 29, 2007. The 5th generation iPhone, the iPhone 4S, was announced on October four, 2011, and released ten days later.

An iPhone can function as a video camera (video recording was not a standard feature until the iPhone 3GS was released), a camera phone, a transportable media player, and an Net client with electronic mail and web browsing capabilities, can send texts and receive visual voice mail, and has both Wi-Fi and 3G connectivity. The user interface is built around the device's multi-touch screen, including a virtual keyboard than a physical.

Third-party as well as Apple application program is available from the App Store, which launched in mid-2008 and now[when?] has over 500,000 "apps" approved by Apple. These apps have diverse functions, including games, reference, GPS navigation, social networking, security, and promotion for tv shows, films, and celebrities.

There's generations of iPhone models, each accompanied by of the major releases of iOS (formerly iPhone OS). The original iPhone was a GSM phone, and established design precedents, such as screen size and button placement, that have persisted through all models. The iPhone 3G added 3G cellular network capabilities and A-GPS location. The iPhone 3GS added a compass, faster processor, and higher resolution camera, including video recording at 480p.

The iPhone four has a rear-facing camera (720p video) and a front facing camera (at a lower resolution) for FaceTime video calling and for use in other apps like Skype. The iPhone four featured a higher-resolution 960 x 640 display; it was released on June 24, 2010. In the U.S., AT&T was the only authorized carrier until February ten, 2011, when a CDMA version of the iPhone four launched for Verizon. On October four, 2011, Apple announced the iPhone 4S.

The iPhone 4S added a higher resolution camera (8 megapixel) with 1080p video recording, face detection, and video stabilization, a faster, dual core processor, support for both GSM/UMTS and CDMA on chip, GLONASS support and a natural language voice control technique called Siri. It is available in 16 GB and 32 GB, and a new 64 GB capacity. In the United States, it was announced that new carriers, Dash and C Spire, would start carrying the iPhone four and iPhone 4S in October and November 2011, respectively. On April twenty, 2012, 6 more regional US carriers (Cellcom, Appalachian Wireless, Alaska Communications, GCI, MTA Solutions, and nTelos) have been added in to the list of iPhone service providers.

History and availability

Apple rejected the "design by committee" approach that had yielded the Motorola ROKR E1, a largely unsuccessful collaboration with Motorola. In lieu, Cingular gave Apple the liberty to generate the iPhone's hardware & program in-house & even paid Apple a fraction of its every month service revenue (until the iPhone 3G), in exchange for years of exclusive U.S. sales, until 2011.

Development of the iPhone began in 2005 with Apple CEO Steve Jobs' direction that Apple engineers inquire in to touchscreens. They also steered the original focus away from a tablet, like the iPad, & towards a phone. Apple created the device in the work of a secretive collaboration with AT&T Mobility Cingular Wireless at the time at an estimated development cost of US$150 million over thirty months.

Jobs unveiled the iPhone to the public on January 9, 2007, at the Macworld 2007 convention at the Moscone Middle in San Francisco. The iPhone 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. The passionate reaction to the launch of the iPhone resulted in sections of the media christening it the 'Jesus phone'. The original iPhone was made obtainable in the United Kingdom, Germany, & Germany in November 2007, & Ireland & Austria in the spring of 2008.

On July 11, 2008, Apple released the iPhone 3G in twenty-two countries, including the original six. Apple released the iPhone 3G in upwards of eighty countries & territories. Apple announced the iPhone 3GS on June 8, 2009, along with designs to release it later in June, July, & August, beginning with the U.S., Canada & major European countries on June 19. Lots of would-be users objected to the iPhone's cost & 40% of users have household incomes over US$100,000.

In an try to gain a wider market, Apple retained the 8 GB iPhone 3G at a lower cost. When Apple introduced the iPhone, the 3GS became the less pricey model. Apple reduced the cost several times since the iPhone's release in 2007, at which time an 8 GB iPhone sold for $599. An iPhone 3GS with the same capacity now has no cost to the customer, as of the release of the iPhone 4S. However, these numbers are misleading, since all iPhone units sold through AT&T need a two-year contract costing several thousand dollars, including an early termination fee and a SIM lock.

Apple sold 6.1 million original iPhone units over quarters. Recorded sales have been growing steadily thereafter, and by the finish of fiscal year 2010, a total of 73.5 million iPhones were sold. By 2010/2011, the iPhone had a market share of barely 4% of all cellphones, but Apple still pulls in over 50% of the total profit that global mobile phone sales generate. Sales in Q4 2008 surpassed temporarily those of RIM's BlackBerry sales of.2 million units, which made Apple briefly the third largest mobile phone manufacturer by revenue, after Nokia and Samsung. About 6.4 million iPhones are active in the U.S. alone. While iPhone sales constitute a lovely portion of Apple's revenue, a quantity of this income is deferred.

The back of the original 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. The iPhone 3G was available in an 8 GB black model, or a black or white option for the 16 GB model. They both are now discontinued. The iPhone 3GS was available in both colors, irrespective of storage capacity.

The iPhone has garnered positive reviews from such critics as David Pogue & Walter Mossberg. The iPhone attracts users of all ages &, besides consumer use, the iPhone has also been adopted for business purposes.

The white model was discontinued in favor of a black 8 GB low-end model. The iPhone has an aluminosilicate glass back & front 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 2011,0 months later.

Users of the iPhone reported dropped/disconnected phone calls when holding their rings in a positive way. This became known as antennagate.

On January 11, 2011, Verizon announced in the coursework of a media event that it had reached an agreement with Apple & would start selling a CDMA2000 iPhone. Verizon said it would be available for pre-order on February, with a release set for February0. In February 2011, the Verizon iPhone accounted for.5 percent of all iPhone commercial impressions[vague] in the U.S. on Millennial Media's mobile commercial network. On March, 2011, at the iPad event, Apple announced that they have sold 100 million iPhones worldwide.

On Tuesday, September 27, Apple sent invitations for a press event to be held October, 2011 at0:00 am at the Cupertino Headquarters to announce details of the next generation iPhone, which turned out to be iPhone 4S. Over a million 4S models were sold in the first 24 hours after its release in October 2011. Due to huge volumes of the iPhone being manufactured & the its high selling cost, Apple became the largest mobile handset seller in the world by revenue, in 2011, surpassing long-time leader Nokia; however, later that year, it was surpassed by Samsung, a major manufacturer of Android rings. American carrier C Spire Wireless announced that it would be carrying the iPhone 4S on October 19, 2011. In February 2012, ComScore reported that 12.4% of US mobile subscribers use an iPhone. The iPhone 4S launch was also the largest launch for any smartphone in the history of mobile gizmo market.,,,,,,,,,,,,,,
