I have an original iPhone that is unlocked and jailbroken, and I am on at&t right now with a prepaid plan. But I am kind of bored with it, and really want to have a data plan that I dont have to pay out the wazoo for. Are there any wireless services that are in the U.S. that I can use my iPhone with and have a decent data plan, and possibly a decent amount of talk and texts? Or is this out of reach?
