Motorola has been heavily criticized by developers and consumers for locking down the boot loader on their devices. In its defence, Moto said that carriers also play a part in locking the boot loader on their phone, and that they will unlock boot loader on their handsets sometime in the 2nd half of this year.
Now, the folks over at BriefMobile, have somehow managed to get their hands on a test build of Android 2.3 Gingerbread for the Atrix 4G. The test build allows them to unlock the boot loader on their Atrix 4G, by simply using the fastboot oem unlockcommand.
Below is a video of the Atrix 4G boot loader being unlocked :
It is not confirmed whether the final build of the Gingerbread update for the Atrix 4G, will allow users to unlock the boot loader on their handsets.
BriefMobile does state that they have confirmed with representatives from Motorola, about the possibility of unlocking the boot loader in the final build of the Gingerbread update.
If Motorola remains true to their words, then this move will definitely please all the Atrix 4G owners out there. An unlocked boot loader would mean faster un-official Android updates, AOSP ROMs, custom kernels with Overclocking and under-volting support etc.
