i-PHONE 4S

The iPhone 4S is a touchscreen slate smartphone developed by Apple Inc. It is the fifth generation of the iPhone and retains the exterior design of its predecessor, the iPhone 4, but is host to a range of improved hardware specifications and software updates.  The phone added a voice recognition system known as Siri and a cloud storage service named iCloud. Some of the device's functions may be voice-controlled through Siri.
The iPhone 4S was unveiled at Apple's "Let's Talk iPhone" event on October 4, 2011 in Cupertino, California. Apple started accepting pre-orders requests for the iPhone 4S on October 7, 2011 in seven initial countries (United States, Canada, Australia, United Kingdom, France, Germany and Japan) with the first delivery date set for October 14, 2011 and available on that same day for direct in-store sales in those countries. It was released in 22 more countries, including Ireland, Mexico, and Singapore on October 28.
It is available for 100 cell service carriers in 70 countries, including eight carriers in the United States. In Japan, it is available for au and Okinawa Cellular for the first time. For US customers, while pre-orders for purchasers buying contracts started on October 7, 2011, unlocked (contract-free) sales started on November 11, 2011. The Associated Press said that AT&T described early iPhone 4S demand as "extraordinary".

History

Speculation about Apple's next generation phone, including various specifications and a predicted name ("iPhone 5"), were widespread in the time preceding its debut. After the iPhone 4S was announced, there was some disappointment about the new phone's name. As early as May 2011, some leaks had a fairly accurate description of the product including the name "iPhone 4S", the A5 chip, HSDPA, new/better camera, and Sprint carrying.

There were no external differences between the iPhone 4 CDMA model and the iPhone 4S; all changes were internal (slight external differences between the iPhone 4 GSM model and the iPhone 4S exist, as said differences existed between the CDMA and GSM models of the iPhone 4). It has been described as a "dramatic leap forward in technological innovation and sophistication...".

The iPhone 4S was unveiled at Apple's "Let's Talk iPhone" event on October 4, 2011 in Cupertino, California. The keynote was the first in which Tim Cook led since the Verizon keynote earlier in the year. It was also Cook's first product launch without Apple co-founder, Steve Jobs, whose health was deteriorating and died the day after the announcement of iPhone 4S. Tim Carmody of Wired praised Cook for focusing on company achievements, calling him a "global business thinker" and a "taskmaster".

At the “Let’s Talk iPhone” event held by Apple on October 4, 2011, Mike Capps demonstrated Epic Games’ Infinity Blade II, the sequel to Infinity Blade, on an iPhone 4S. Capps boasted that the game uses Epic Games’ Unreal Engine 3 and features the same graphic techniques used in the Xbox 360 game Gears of War 3.
