Latest rumored AT&T launch date for the the Motorola Backflip: March 7, for $324. That comes from an unidentified source talking to Phandroid. Why March 7? Why not. And if the price point is correct, that could bring the Backflip down to about $100-$150 after contract subsidy, which lines up with the supposed target market, which is the younger crowd.
That said, this is all very unofficial and very likely to change. Stay tuned. (And in the meantime, check out our hands-on with the Backflip.)
