Today when I set up my new phone from an iCloud restore it asked for the password for all accounts who have content on that phone. This included obviously my main account, my wife's, and an old one of mine BUT it also asked for 2 weird accounts. One was something like firstname.lastname@example.org and another was a Chinese name like email@example.com neither I recognized. I obviously didn't have the passwords for these so their content didn't come along with the restore but I really wonder what it was. Does it have anything to do with being in the Beta program? (or installing the generic Profile which allows users to enter the Beta program)?
