RIM's rumored 10-inch BlackBerry PlayBook may have already been scrapped to refocus more of RIM's efforts on the company's long-mentioned "superphone" using the same QNX-based OS as the seven-inch tablet. A rumor Tuesday alleges that all work has stopped and that most of the remaining PlayBook focus is on LTE-based 4G PlayBooks, which should ship in October. The N4BB insider didn't know for certain when the phone would ship, but RIM's CEOs have usually put it in early 2012.
