I broke a contract on AT&T to change to Verizon the service was that bad. Nothing like dropped calls all of the time. Their 3G was not notably faster than 2G. I'd get calling errors that could only be fixed by a hard reboot. After changing to Verizon, I've had 0 dropped calls in a month and only once had an issue calling someone. I travel all over the west coast and Verizon's network is far superior.
