I'm on AT&T. I've been with them for a few years now and I can't say that I like their service, I've just been tied to them because of stupid contracts. I have a Sony Ericsson T616. The phone has a lot of great features but the reception sucks on the phone. I heard that was a problem with the phone itself that was later addressed in newer models of the phone. I'm looking into upgrading but I'm sure that will come with another contract of some sort.
