I just have a quick question. I have heard in the past that when people give their phones away to family members, or sell their phones to other people, that the buyers have received text messages that were sent to the original owner of the phone. I am passing my iPhone 4 down to another family member, and would like to ensure that they do not get the text messages that are intended for me. How exactly do I do that? Do I simply unregister the phone on Apple.com? Or is there something else to it? I assume that I will have to restore to factory settings in iTunes as well.
