iOS 4.1 device would be compatible with Apple's Game Center mobile and social gaming platform? We're sorry to say that's not the case. Initially it was looking like both the iPhone 3G and second-generation iPod touch would be left out, having to take their copies of Kickety-Kick Ball Bounce Out and go home. But, Apple is now confirming that second-gen touch models will be included after all, however the iPhone 3G is still not invited, nor are first-gen iPhones and iPod touches. That means the final compatibility list includes the iPhone 3GS and 4, along with second, third, and fourth generation iPod touch models. Everybody else: you're out.
