I like alltel or cingular, currently have alltel. I use to have verizon but they totally screwed us with that one!!
They charged me outrageous prices for calling someone in california who only spoke spanish. Hello I never called anyone in california and I don't even know spanish and I was the only one to have the phone, no one else used it, go figure!! When we called them about it they would not due a thing and called us everyday to harass us because they wanted us to pay the bill and one I am not about to pay a bill for someone I did not call and two they wanted a bank number and would not lets us pay any other way, so we said forget it!!!
I heard of other people who have serious problems with verizon, I guess it depends on where you live if you will get good friendly service from them or not.
