The AT&T voice coverage here isn't that great, I do get dropped calls a little more than I should but both network should be getting a full upgrade in the Chapel Hill area. But perhaps dropped calls are inherent in the way AT&T implements GSM.
I'm just curious but if you have an AT&T iPhone, were you able to notice the difference between CDMA, GSM, and WiFi?
