Very interesting. I don't get paid until Monday. So, I will keep shopping for the best price until then. But, the 3 times I have taken my 7100t in for service, in 2 different states, the issue of where I made the purchase never came up. The reps in the store saw a T-Mo branded unit, with T-Mo service, and helped me as best they could. I have waited several months for the 'G' because it looks much better than the 'C'. RIM should have the bugs worked out by now. That's why they let Cingular beta test the 'C' model.
That's my 2 cents anyway.
