iPhone OS 4.0: Apple announces Game Center, a social gaming network for the iPhone

This is huge -- Apple has announced Game Center, an official social gaming network for the iPhone, coming to the device along with OS 4.0 this summer. So far, there have been a few social networks vying for an audience in the form of OpenFeint and Ngmoco's Plus+ system, but Apple's going official, bringing in friends lists, leaderboards, achievements, matchmaking, and so on all to the iPhone themselves.

Jobs said on stage in Cupertino that they will combine GameCenter with the App Store's over 50,000 games and entertainment titles. It'll be extremely interesting to see how Apple's network interacts with App Store titles, and it looks like OpenFeint and the like have some serious first-party competition.
