Just announced in Apple's Keynote was news that Game Center is (finally!) coming to iPhone's in iOS 4.1. It bears the new, greener look we saw back in July and, as Steve Jobs noted, has a heavy focus on multiplayer. Beyond playing games with friends, there's matchmaking and leaderboards across multiple games; it's more or less Steam for your phone.

Jobs says iOS 4.1 - and thusly, Game Center -- will be arriving "next week," though it won't be arriving on iPad until iOS 4.2 in November. We'll be getting our Canabalt scores as high as possible before next week.
