As I have seen people talk about the debate between the two it seems to come down to cost and features vs. coverage. For those in a corp environment with bills being paid, Cingular seems to win out due to coverage. I have read here that if there is any T-mobile signal, you won't move over to the other network. I am not even sure you can force another carrier on the 8700.

With Cingular, i know that the 850 band covers those areas and really do use it quite frequently.
Does anyone using TMO that has an 8700 or other device that has 850 band know wether you roam on the 850? If this is not restricted, then there is no reason why the Cingular coverage would be superior, is there????
