I've used both AT&T and Verizon as cell carriers, and I am much more pleased with AT&T. I have never had a dropped call, and I get connection everywhere including the middle of the ocean on a cruise. Verizon never gave me signal if I was anywhere near metal or a tall obstruction, like trees/forests. AT&T also offers MUCH faster internet, which is a must have for me. The only reason I would consider going Verizon is for the Droid, and I'd probably switch back to my iPhone after a month or two.
