For anyone considering switching to Verizon to "get back" at AT&T, please understand that they both can be pretty crappy companies.
At least one major carrier lied about its 4G coverage, FCC review finds
Of course, AT&T (and the others ) probably overstates their coverage as well, but Verizon is the one people are complaining about. Having recently switched to Verizon for wireless service, I can say I am disappointed with the local coverage, and I am not even in a particularly rural location. I will be switching back to an AT&T MVNO in December, so my wife doesn't kill me.
