Give Thorsten Heins credit for being gutsy. The BlackBerry (NYSE:BB) chief skewered Apple's (NASDAQ:AAPL) iPhone as old technology ahead of the U.S. launch of the new Z10 handset.

Say what you will about this being Heins' pot-kettle-black moment. It doesn't matter. What does is that he's openly challenged Apple and CEO Tim Cook to the tech equivalent of a fistfight, and the whole world is watching to see if he'll be knocked right back on his keister.

Can BlackBerry win? What little data we have so far says the Z10 is a mild seller. But retail sales isn't where the fight will be won or lost, says Tim Beyers of Motley Fool Rule Breakers and Motley Fool Supernova in the following video.
