but mine is that the 7100t reboots about once in every 4 or 5 calls. I'm on Long Island as well (in case that's a factor), no BES and BWC. I never had it with 3.8 so this last reboot (just today) was the "last straw" and I'm in the process of trying to downgrade to 3.8. Unfortunately it's NOT going smoothly but we'll see.
The fact is that at least SOME 7100ts DO reboot in the middle of calls, for whatever reason. Therefore you DO stand a chance, if you go with a T-Mo 7100t, of having the same happen to you. Add to this the response you got from T-Mo "Tech Support" (who HAVE been told of the problem by people who have experienced it) and you have a recipe for throwing money down the drain.
Hey, it may be a data issue or a flaky battery or a loose SIM, I don't know. Problem is T-Mo can't or won't help.
You've been warned.
