App still supported on 2nd-gen Touch
Apple has reset all user IDs for its Game Center multiplayer service, requiring beta users to resubmit their nicknames. The service will allow users to challenge other players, set up matches, or engage opponents via automatic pairing. The app will also serve as a portal for viewing rankings or taking a look at other games.
The list of supported devices has also been changed, dropping the iPhone 3G despite its presence during beta testing. The service will only work with the iPhone 3GS and iPhone 4, or the 2nd-, 3rd- and 4th-generation iPod touch.
Game Center is expected to be launched on Wednesday alongside iOS 4.1. [via 9to5Mac]
