Samsung SGH-D840
D840 vs. T629 for T-Mobile
They look very similar, however we've heard that the camera will be downgraded to 1.3 megapixel, the display will be downgraded to 176 x 220, and the internal memory will be downgraded to 21 MB. On the plus side, the T629 will add GSM 850, and possibly voice recognition.
If anyone has concrete info about these differences, or any other data about the T629, please let us know! 🙂
