We already know that the Big Four will be getting their own respective renditions of the Galaxy Note II. We also expect that it'll also be part of a unified release much like the Galaxy S III. We've even seen how Verizon defiled its home button. Turns out leaving its mark on the face of the device wasn't enough for Big Red, though; the carrier has also done some work to the bootloader.
They locked it, and there probably won't be any official method of unlocking.
