I love AT&T- it is different everywhere of course, though.
In KY I hear nothing but complaints about Sprint- if you aren't near a major city, they suck. You can't get service in most of KY- almost 2/3 I think. A friend of ours owns a cell phone store and he is a Bluegrass cellular distributor (not affiliated with anyone) and he said that if you live in Louisville or Lexington Cingular or AT&T are the best carriers, and I have never once had a problem with customer service!

Sprint here, just doesn't cut it! And Verizon screws EVERYONE on their bills- we have a corporate account with them and have 15-20 complaints a week from JUST our office- we have 10 area offices so imagine how many they get! The really do PURPOSELY mess up your bill, so BE CAREFUL and read it over well!
