For what it is worth, my entire family and I recently switched from T-Mobile to AT&T Wireless. Monthly cost for the family was the same, coverage, where we live, is much better. Phone selection (at the time and now) favors AT&T.
Our company is moving off of T-Mobile also. Lack of coverage, dropped calls and general customer dissatisfaction are the reasons.
I can tell you ever dead spot T-Mobile has around me for 50 miles. I drive through a lot of them daily. Cost means nothing if the calls are dropped :(
