I'm about to sell my phone within an hour, I'm backing it up right now but when I erase it, should I do it via the "RESET" option in the iPhone settings or have iTunes do it? I've heard that the Reset option can take hours to complete and I need to empty this thing now. Do I just uncheck everything in iTunes when I'm syncing and that should be fine, or is there an option in iTunes to erase the phone QUICKLY (within an hour, I need to know quickly!)
