My old Apple ID is popping up (and it won't let me change it). Help?
While trying to restore my new phone from my iCloud backup, I can sign in with my current one, but then the old one will ask me to sign in after I choose which backup to use. Because the old ID no longer exists (but is somehow still connected to my current account?) I cannot "reset the password" or even login with a password because it doesn't exist! This is incredibly frustrating; I would just like to get my new phone up and running.
