What's this? The second coming of the iPhone 4? Sure enough, Tim Cook just pulled the covers off of the hotly-anticipated iPhone 4S here in Cupertino, making 2011 the first year in the company's current stint in the smartphone business that it chose to launch three new handsets (Verizon's CDMA iPhone 4 included, of course). On the outside the 4S looks exactly like its predecessor, but on the inside it's "all new." Apple has jammed a dual-core A5 CPU inside alongside a new dual-core GPU that supposedly boosts graphics performance by up to 7x.
