It was something of a black eye for BlackBerry when it came out that Sprint wouldn’t be carrying the all-touch Z10 BB10 smartphone. A huge relaunch, integral to the company’s future success, and one of the four major U.S. carriers was taking a pass on the first hardware. But the carrier is going to sell the keyboard-toting Q10, and will also sell what could be a Z10 successor, complete with touch-only interface, later in 2013.
