I just have a simple question about erasing all the contnt fom my iPhone. I'm going to be giving my 3g to a buddy, and had personal information on my phone. I performed "Erase all content and settings" then pluged the phone into iTunes to somewhat activate it. I removed th sim and now I'm wondering if thats all I need to. Is all my media and information completely gone, or can it be recovered by some hack or program?
