The fine folks at CrackBerry.com and The iPhone Blog put the beta of Apple's upcomng iMessage (from iOS 5) against BlackBerry's BBM. The video above shows how both interfaces look and act as well as a simple back and forth test on both messaging platform. iMessage is faster in these tests, but consider that there are far fewer users running iMessage (which is available only as a developer me beta right now) than BBM. Still, one can see that Apple thought this over very well and anyone who has been waiting for this sort of almost realtime messaging platform on iOS should be really excited. Consider too that while BBM is for BlackBerry smartphones (not the PlayBook, yet). iMessage will work on iPhone, iPod Touch and iPad.
