Apple previews Game Center social gaming platform for iPhone OS
Apple just announced Game Center, which is a social gaming network for the iPhone -- it sounds a lot like Xbox Live, actually. It's has a friend system, leaderboards, and achievements -- and we're guessing it'll blow up out of the gate, given how many games are on the platform. It's being previewed in iPhone OS 4 right now, and it'll launch later this summer. We're hunting for more info, we'll let you know!
