i sold my iPhone 4s and i need to sign into iTunes to disable the old phone
I sold my grandsons iPhone as broke and it was repaired and now, the person who purchased it needs to unlock the phone. I remember my passcode . But now he needs to sign into iTunes. I don't remember by other information needed to access the phone. I need to delete my information on the phone. Can someone help me. I do not have access to the phone. My grandson has a new phone which is signed into iCloud. His old phone does not show up in iCloud, just the new one.
