Well, I have an offer to sell my iPad1 (32GB + 3G) for $500 to a friend. Definitely a good deal! But, I need some advice. How do I completely wipe my Ipad1 so that it disconnects from my credit card and all my passwords, etc? Do I just restore it? AND MAINLY, after this is done, will the backup from my Ipad save so that I can use it on my iPad2? I want to make sure that my backup is kept so that my iPad2 has exactly what my iPad1 has on it now. And finally, do I take the AT&T SIM card out and keep that, or how do i transfer that so it disconnects from my data plan/account? THANKS!
