[barski]

Just one day after the news of unlocked Gingerbread bootloaders on the Atrix reached the net, developers have packaged up a bootloader unlock file that will allow Atrix users on all builds (even Froyo) to unlock. The full guide resides below this text. It’s a fairly simple process, but we warn you that unlocking your bootloader may void your warranty. BriefMobile cannot be held responsible for any bootloader unlock-caused mayhem. Flash this unlocker at your own risk!
