iPhone question [View all]

Awhile back I changed my Apple ID to my new email address and changed my password at the same time. Then something happened and my ID reverted back to my old, discontinued email. Since my password is hidden I’m not sure if it’s the old or new one, and I’m not even sure if I remember my old one. At first I wondered if my phone had been hacked but so much time has gone by without incident that I’m thinking my attempt to change my ID was simply unsuccessful.

Now, however, I really do want to make those changes but am afraid to try for fear of getting locked out of my phone since I can no longer access email sent to that old address.

Suggestions welcome!
