Apple ID problem
A friend has asked me to assist with this problem, but I know little about Apple technology. Here's a brief synopsis:-
Originally, he had an Apple ID which reflected his AOL e-mail address. This address has long since ceased to exist. Recently he went in and managed to somehow change his ID to a BT e-mail address. This appears to work ok when going directly to the Apple login page. However, if he selects one of the many pending updates on his iPad, it always comes up with the now old and non-existant AOL address, and there doesn't seem to be any way round this. We know what the old address was, but he's long since forgotten the AOL password.
How do we get rid of this old AOL address ID?
