my friend's e-mail doesn't exist. She used the e-mail as an Apple ID and she share her ID to her friends to use with their iPhones. One of her friends change ID on iPhone to another ID. Somehow it doesn't work and the previous e-mail disappear from the system. I'm not closed to this friend but I've been asked for help from them. Any idea what happen? If I create the same e-mail and apply to Apple ID, all things will be back or not?
