What the Rumors Say
RIM is no less immune to leaks than any other company, so a fairly reliable overview of this upcoming BlackBerry is already available.
Like its predecessors, this handheld is expected to have a full QWERTY keyboard, but it will also include many of the new multimedia features that debuted on RIM's latest smartphone, the Pearl.
This means it will also include a a miniSD card slot to supplement its internal storage.
It is also supposed to have a trackball like the Pearl, not a scroll wheel as previous BlackBerry handhelds do.
Nothing unexpected here: 64MB of internal (expandable) storage, quadband GPRS / EDGE, GPS, and an MP3 player, with no mention of a camera.
