With the most recent update to Xbox Live users can access Facebook and Twitter, but as far as accessing Xbox Live friends lists and information from external sources, solutions are few. Now with 360 Live, an unauthorized iPhone and iPod touch app released to the iTunes App Store, users can access their complete friends list, compose and receive messages, manage friend requests, compare achievements with friends, and more.

Pretty cool. Not sure what players think just yet, but probably worth checking out. Here it is on the App Store for 1.99.
