Good news for international Atrix users today. It seems that forum users stevendeb25, Samcripp, and the2dcour were able to find a piece of Motorola firmware that contained a bootloader unlock for Orange UK devices. Testing is still underway with the unlock, but this could mean unlocked bootloaders for countless international Atrix users.
Unlocked bootloaders will allow Motorola Atrix users to flash custom kernels and ROMs. Update: link after the break.
