I recently left my job. I changed my email address I was using for my Apple ID as the current one was with my work email. Used it to switch on my iPhone 4 and iPad mini. Worked. Now it is not working or recognizing it on either. Can't use them. Email it's asking for no longer exists. I can't find anyway to reset to my new email address again???? So I can update, use apps, use phone, etc. thank you!
