I changed my Apple ID from an old email address to a new one. Everything is fine to sign into iCloud, to go to the App Store. BUT, when I go to Find My iPhone to erase an old device I am getting rid of, it defaults to the old email. Help?
When you change your AppleID from an old email to a new email address, how do you get Find My iPhone (Erase) to use the new AppleID? It keeps defaulting to the old email address, and won't recognize it to let me reset a password, either. What is the solution?
