Here’s something that will definitely make all the AT&T BlackBerry users happy. Engadget Mobile was sent some specification sheets detailing info about the BlackBerry Magnum, Onyx, Pearl 3G and the Gemini, all of which are going to be headed to AT&T.

There is no confirmed or leaked launch date available right now, but I’m sure these specification sheets will temporarily satisfy you. The only actual photo available in these sheets is of the Onyx and the others are just abstracts, but the specification sheets give us great insight on what to expect from these upcoming devices.

For those that were not interested in the Pearl Flip 8200 series, it looks like a new 3G Pearl is in the works.

These specification sheets being for AT&T doesn’t necessarily mean other carriers won’t get these BlackBerry devices as well, but AT&T may be getting a first crack at them.

Check out the rest of the sheets after the jump.
