Resurrecting old iPhone 4
i found an old iPhone 4 of mine. I would like to get it working again. Problem I lent this to a friend of mine she used it then got on someone else’s account I asked for it back she mailed it back. Ok, she can’t remember Apple ID password, I was able to remove all her other info through iTunes, but I can’t get past hello with out the id password. I know the phone is old school but it is small and I very seldom use an iPhone. Can I get this unlinked to her we are both elderly and she won’t be any help.
Thank you
