Apple's Game Center app is a social gaming network feature added to iOS 4, which can provide a centralized experience for gamers on the iPhone and iPod touch -- similar to Microsoft's Xbox Live. Game Center, which went live in June and is scheduled to launch later in 2010 promises to allow gamers to invite friends to play a game, start a multiplayer game through matchmaking, track their achievements, and compare their high scores on a leader board.
No word on how b3 addresses the iPhone 4's nagging proximity sensor bug.
