As we near the final stages of development on our latest project, we’re scanning the radar to see who’s going to be top-dog in the iPhone social network arena.  Up to this point, we have been loyal fans of OpenFeint, but we’re keeping an open mind.  Our latest challenge is allowing players to invite friends to a game via their buddy list.  However, OpenFeint doesn’t seem to have any way to determine who’s online or offline.  We’ve dropped a line to Plus+ as well as OpenFeint to see if either can offer a solution.  May the best platform win!

(oh and yes, these are the only two platforms that matter right now)
