Apple's new Game Center page lists the iOS devices that will let you get involved in this whole playing games with other people thing that's happening soon. Second-generation iPod Touch owners: you're in luck! iPhone 3G owners: you're not!
Game Center, which will be arriving with the imminent iOS 4.1 update, will allow users to join up with friends to do battle in epic cathedrals and elsewhere - unless, of course, you're still riding around on an iPhone 3G, in which case you're stuck flinging angry birds by yourself.
The second-gen iPod Touch has a slightly beefier processor, which could have something to do with it, but at this point, Apple's stance is painfully clear: iPhone 3G is old and busted. [Apple via MacRumors]
