I have a T-Mobile compatible Nexus One but my carrier is At&T. Should i shift to T-Mobie 3G or should i continue using At&T 2G. I am in Connecticut and not sure how the 3G coverage here is for T-mobile.
Have you thought about getting a pre-paid SIM and see how TMO service is? Enter in your address and see what the voice and data would be like. Don't know if you can get 3G with pre-paid, but would be interesting to find out.
