Samsung has been busy once again, this time with some new mobile phones, the Comeback and the Gravity 2. T-Mobile has announced that these phones will be hitting their network soon.

The Comback is a 3G handset that opens up for a QWERTY keypad, MP3 playback and microSDHC slot, as well as a 2 megapixel camera.  The Gravity 2 has pretty much the same features, but it slides up to reveal its QWERTY.  The price for the Comback is about $130 (for 2-year deal with $50 mail-in rebate), but the price of the Gravity 2 is to be announced.
