Pop the champagne!  AT&T just officially announced their first Android handset, the Motorola Backflip.  Okay, I’m way overstating my excitement, but it’s good to see Big Blue jump on board with the mobile Google OS.

The Backflip is a Motoblur device and unlike other flip phones is a reverse flip.  What’s that mean?  The QWERTY keyboard folds onto the back of the handset as opposed to over the screen.  Features include WiFi, a 5 megapixel camera, 3G connectivity, a 3.1-inch touchscreen display and more.

The Backflip will launch on March 7th for $100 after a $100 mail-in-rebate and 2-year signing.
