I have long since stopped using the email address I used when I signed up for iTunes, which was also the email address I used to create my Apple ID. I now use a different gmail address both as my primary Apple ID and iTunes account, and the old email address has long since been deleted from both my iTunes account and my Apple ID. My problem is that the old email address keeps popping up. Every time I set up a new iPad or iPhone it always pops up asking for a password. I just hit "skip" and go about my business, but it's beyond annoying to always have that pop up when I'm to input my Apple ID on a new device. Any idea how to get rid of an old email for good?
