help with an iphone..........what company?

well unless you buy a iphone off ebay and unlock it you have to use att as your service. Personally i have att and it is great and works well for me

Unless you get an unlocked one you have to use AT&T. I have AT&T and an iPhone and I like them both. AT&T is so much more reliable where I live because the Verizon/Alltel towers go out a lot. They not only go out a lot near where I live but I have a friend that goes to school in another city and he told me they go out like at least twice a day there.
