Also what is the difference between BlackBerry and BlackBerry OS and
Bada / Bada OS?
Excellent question. :)
I'm also assuming this should be a handheld ? (handheld RIM
Tablet OS 807)
That'll be the BlackBerry Playbook 7-inch tablet, which runs a precursor to BB10. For OS breakdown purposes, it should possibly be grouped with BB 10 and both should be separate from classic BlackBerry.
