I am in the Navy and am required to move around a lot. I also do a lot of traveling inside the US visiting family and friends. My T-mobile phone only works in a few spots of the US. I always see others with version and Cingular using the phone, but mine has no antenna. I thought maybe I could get a new phone (with another 1Year contract) and that would fix my problem. I was wrong. I now have a cell phone that works less than 35% of the time while these other folks walk around me using the cell phone all the time. I will make my move to cingular after this contract.
