What I would like to do is sell my old iPhone 3g to someone who doesnt want to use AT & T at all (Basically use the phone like an iTouch) He wants to be able to sync his library and restore the phone. How should I do this? I will be activating my new ip4 tomorrow and then I want to sell him the phone, should I leave the sim in or take it out? Im not willing to jailbreak. Will the phone being deactivated by the new one being activated be enough? Or will I have to do something else? Thanks.
