iPhone 4S Smartphone Information Center
Apple's 5th Generation iPhone is the iPhone 4S. As it was with the iPhone 3GS, the "S" stands for speed, as the updated iPhone has a faster, dual-core processor and a more powerful GPU than the iPhone 4.
Available on the AT&T, Verizon Wireless and Sprint networks, the iPhone 4S features roughly the same design as the CDMA iPhone 4 but has a hybrid transceiver which allows the device to operate on both CDMA (Sprint, Verizon) and GSM (AT&T) wireless networks.
The big story with the iPhone 4S is its internal hardware: it has a dual-core A5 processor in addition to a dual-core graphics processor. These two components allow the phone to perform faster than previous iPhone models, and make possible one of the most important features of the iPhone 4S, Siri.
Siri is a voice-interface feature built into the iOS 5 and iOS 6; however, it doesn't work on older models because of the processing power required. Based on technology acquired in 2010, Siri allows a user to interact with the iPhone 4S naturally with his or her voice. And, in turn, provides the iOS with a way to provide the user with information through text-to-voice technology rather than relying solely on the touchscreen to display information.
Other changes include an 8MP primary camera, a redesigned antenna system for 14.4Mbps data download speeds (AT&T, HSPA+ only), and improved battery life.
iPhone 4S is available with 8GB of flash memory storage as of September 2012. The price on contract is $99. Legacy models come in 16GB, 32GB and 64GB capacities; with the release of the iPhone 5, these older models may vary in price from retailer to retailer.
