I want to use my old email with new Apple ID
For some reasons I wanted a new Apple ID but wanted to kept my same old email. What I did was changed email of my current(example@gmail.com) Apple ID to (example123@gmail.com) and then tried to make a new ID with my old email(example@gmail.com) but when I tried to create ID, it still said that my email is used with another id. But I actually changed that old email with a new one! Please solve this issue. I'm very upset. Hope some answers soon......
