Apple finally revealed its long-awaited “iPhone 5” Tuesday: it’s actually called the iPhone 4S, and will be twice as fast as the wildly popular iPhone 4. The new model looks exactly the same, but features a new dual-core processor and graphics capabilities that will make the phone seven times faster at operating games. It also sports an improved camera and a sharper version of the “retina” display unveiled on the iPhone 4. Apple has revamped the phone’s antenna, which initially caused problems for iPhone 4 users because reception was affected by how the phone was gripped.
