I dont know about the rest of the country, but apparently AT&T is doing repairs and service to almost every town here in Tucson, AZ. They started doing this right at the beginning of the iPhone 3GS release. In other words: when many people, including myself, switched from Verizon to AT&T for the iPhone, we encounter crappy cellular service because as much as 12 towers in my immediate area are disconnected during these "repairs". That REALLY looks bad for AT&T considering this is the first impression I get of them. The representative did say that this is going in several places across the country so if you just switched or are a regular member and your service is suddenly crappy, just call to see about outrages and this may be the reason.
