I recently upgraded both of my phones and now I want to sell them on Ebay. Other than resetting the phone through the settings app is there anything I should do to make sure that the phone is safe to sell?
Do I need to do anything special to delete anything on the SIM card?
Should I not include the SIM card with the phone? I'm not sure if they can get one for free at AT&T.
These are AT&T phones so I would have to sell them specifically as AT&T, they can't be easily modified to run on other networks?
