Today I bought 6S+ 128GB on ATT Next. During first restore from backup something went wrong and not all apps synced, and for some reason some apps were super laggy. Like if I press on address book, it would not respond at all, and then in 2-3 seconds would open it. So I decided to restore to factory setting. And once I restored I got a message from iTunes that my phone has been unlocked! Very interesting how it happened? Anyone have done the same and got unlocked message?
