So I'm selling off an old iPad, and was wondering if there's any special things I should do when wiping it clean? I'm mostly worried about the various jailbreak stuff on it. I just want to make sure that I can wipe the hard drive completely clean in a way that will prevent a future owner from using tools to recover "deleted" data. I was told to just turn off Find My iPhone, sign out of iCloud, and then use the "reset all data" thing in iOS. Will that safely nuke EVERYTHING on the hard drive, though? I was also told that I have to "remove the SIM card" before selling it...why do I have to remove the SIM card? Doesn't that disable the 3G? I'm wanting to sell it as a 3G iPad, not a WiFi iPad.
