Had the Treo 600, and 650 with TMO. Went to the 7105t and never looked back. Hands down the BB platform has been the most reliable. You are correct, TMO has some of the best prices on data (BB etc) around. You will not be dissapointed. Had the 8703e with VZW, and know someone with the 8700g who loves it. Take it for a test drive, and enjoy the decrease in random restarts and resets.
