I just sold an old iPhone on ebay. I want to make sure I wipe all of the data from the phone. I did the system reset (within the iPhone's own software, not connected to my MBP), and it seems to have cleared everything. (There wont be any recoverable data, will there???) The only thing it keeps, however, is the MY PHONE NUMBER IS. I don't want the buyer to find out my personal phone number (he has my ebay contact info, that should be enough). How do I wipe that too? Is it linked to my SIM card? (When I remove the SIM card it still shows). Is there a way to run the iPhone without a sim card??? Whenever you reset the phone's software with no SIM installed, you only get the option to make emergency calls... Any help would be appreciated, so I can ship this off to the buyer today! Thanks!
