iOS 6 coming to iPhone 4S, 4, 3GS, new iPad, iPad 2 and iPod Touch
 

We know what we're getting from iOS 6 and won't have to wait long for it. Apple's new mobile OS will land on existing phones, tablets and media players on September 19th -- a week from today. As was mentioned when we first saw iOS 6, the cut-off appears to be the iPhone 3GS, while tablets starting from the second iteration will be able to access Apple's new feature set.
