Sold my 16GB wi-fi on eBay last night and the winner asked that I please not reset the device to factory default. Is there a way to leave it with software installed and take my personal info off? (iTunes account, etc.) I would't do this unless I could do a DoD type wipe on the empty storage space to prevent recovery of previosly stored data. But all that just sounds pretty unreasonable when it seems like resetting the device is the normal thing to do. What do you all think?
