Crackberry claims to have gotten hold of an official RogersBB 10 training manual that may or may not add to your anticipation of January 30th. The leak is a Powerpoint slideshow that apparently contains screenshots from an online course for sales people -- so there's been at least one twist in its journey before it reached us, and that's reason in itself to be a bit cautious. Nevertheless, the document repeats familiar claims from RIM about its new flagship smartphonehaving "best in class" HTML 5 browser compatibility and performance. It also highlights the promise of 70,000 QNX apps in the re-named BlackBerry World, although we don't know how many of those are totally new, ported or perhaps cross-compatible with older QNX devices. Finally, a few more specs are detailed in the hope of enticing tech-minded shoppers, with reference to a Snapdragon S4 processor, a 1,800mAh battery and a 356 pixel density that tallies with what we've already seen of the 4.2-inch 720p screen.
