I just bought a brand new iPhone SE. I had an iPhone 4S. I chose to restore the iPhone SE from the iCloud backup created from the iPhone 4S. It seems to work but every once in a while a message will display telling me to "Enter the password for my Apple ID firstname.lastname@example.org". That is not my email address, nor have I ever seen or heard of such an email address. It has absolutely nothing to do with me. WTF is going on? Needless to say I don't know their password, and the iPhone won't even let me change the incorrect Apple ID to a correct one. Regardless, I'm signed in with my Apple ID and the device works fine, my apps are downloading and all is well. Except this random message that pops up every now and then. What's going on?
