DevDroidian tweeted these pictures earlier today. Looks like it may be another Sense UI device.
slashgear has just done a really nice review of the BACKFLIP by AT&T. This phone has been known recently as the first Android without Google Search, it was replaced by Yahoo Search. Motorola has been cranking out Android devices since the release of their first, the Cliq. This is their fourth release for the US market and the fifth overall, this is quite an amazing feat considering that they entered on the scene late in the game.
