«Can you provide more information? When you indicate that she changed the ID for her phone, do you mean that she changed her existing Apple ID to a new email address, or that she created a brand new Apple ID?» When she left her job nearly 3 years ago, she changed the email address associated with her Apple iPhone 4S from her work email to a personal one. We followed the instructions on the Apple Knowledge base, removing the old email and substituting the new one. The backup ID, a personal one, remained the same. Note that this change was made under iOS 6 (or earlier?) before the existence of Activation Lock.
«Are you indicating that she did not sign out of iCloud on the phone before changing the ID?» Correct. Note that the backup method was set to iTunes on her home computer, not to iCloud.
The phone worked fine. All the apps and data carried over. Find my iPhone worked to locate the Phone and Play a sound. She never used iCloud for any purpose. Contacts were backed up to her computer. BUT every once in a while (and every time the iOS was upgraded) a pop up showed up asking for the password for the old ID. One of the choices was "NOT NOW" which she always checked, not to be bothered by this weird request. The phone then continued to function normally. Subsequently, the phone was upgraded to an iOS that had activation lock. As I noted the Find My iPhone worked correctly with her current email address ID. At some point, I suggested to her that she remove this problem by inserting the password (which she had written down in two places). But the Phone would not take the password. Attempting to remove the iCloud account resulted in a request for the old password which was not accepted. A request to Apple to send the password for the old ID to the recovery email address resulted in a reply that no such Apple ID existed.
I tried to get help for her problem on the iPhone board, but received no replies, so we made an appointment at the Genius bar. The Genius spent a lot of time with us. He confirmed the problem, but could not figure out a solution. He did not want to wipe the phone clean, because he said that doing that very occasionally bricked the phone, and, in any case, there would be no benefit, because when we did a restore from backup, the problem would probably be restored as well. He concluded that Apple had removed the ID from its database as it hadn't been used for a long while and the email address attached to it no longer existed. He concluded that it was best leaving things as they were.
It is based on this conversation (and the facts on which it was based) that I made the postings in this thread. Anything to further enlighten me would be greatly appreciated.
