The buzz continues to mount leading up to the January 30th unveiling of Research In Motions’s (RIMM) next-generation BlackBerry 10 platform, but we’re not sure how much is left to learn. Many BlackBerry 10 features have already been announced, we’ve seen RIM’s first two next-generation handsets — the BlackBerry Z10 and the BlackBerry X10 — a number times, and now Rogers’ internal sales manual for BlackBerry 10 devices has leaked thanks to CrackBerry. The manual is packed full of images and it also confirms some specs reported a few months ago, and the full document is embedded at the source link below. RIM’s next-generation operating system and handsets will be unveiled during a press conference on January 30th, and BGR will be on hand reporting live.
