My parents upgraded their Iphone 5 to 9.3. After it loaded they were not able to go any further until they entered their apple ID and password. Unfortunately, they have no idea what their password is. They went to send an email so that they could change their password, however the email connected to their Apple ID has been inactive for the last few years. So they have no ability to get into the email address that Apple has on file to get the new password. Is there anything they can do? Is there a way to change the email address to a new one they now have? Thanks for any input!!!
