Deep inside Sprint stores, according to ppcgeeks user pslim, is a tool called Cellebrite that will transfer pics, contacts and the like from one type of phone to another. And on that tool has appeared the Touch Pro 2, which is showing up as the HTC 6975. See above.
Of course, that does absolutely nothing to point to when the Touch Pro 2 will finally see the light of day on Sprint (or any other U.S. carrier, for that matter). It is, however, yet another stop on the long and winding road that is the launch of HTC's latest and greatest. (And don't worry, folks, we'll get to do this all over again for the Touch Diamond 2, most likely.)
