Social gaming firm OpenFeint is launching OpenFeint Connect, a service to sync your accounts, friends, leaderboards, and achievements across multiple mobile platforms.

As the new API launches into private beta, developers can release their games on iOS, Android, Bada, Windows Phone 7, PC, Mac App Store, and more, and sync the users' OpenFeint data across all platforms.

“We believe games should connect people, regardless of what device or mobile OS they own.” said Jason Citron, founder and CEO of OpenFeint. “With the release of OpenFeint Connect, we give game developers the flexibility they need to take their games and game data to players everywhere.”

OpenFeint has over 65 million users across multiple platforms, and has its social services embedded in over 4,700 games.
