Apple's Game Center is unveiled later on this year. Until then, a company called OpenFeint has been connecting gamers on iPhones with leaderboards and achievements (which is why you'll often see their logo appear in your iPhone games). And while most of the developers signed on to OpenFeint so far have been pretty small, it's starting to reel in the big fish -- Capcom has signed on to hook its games up to the OpenFeint service.
The service will first appear in Capcom's Dark Void Zero and Hatchlings iPhone games, and both OpenFeint and Capcom say they are excited about the possibilities of working together. Of course, the release of Game Center may change the relationship, depending on what features Apple offers later this year. But OpenFeint says they're planning to offer services even on top of Game Center's planned featureset (Capcom has confirmed they want to use OpenFeint X, a platform for serving up virtual goods on the iPhone even beyond what Game Center will offer). So it sounds like even after Apple's official network is released later this year, Capcom will still have a use for its new partner.
