Thanks to a Phantip we just received, I am happy to announce that the Atrix modding community in the UK are rejoicing over a new turn in development for the phone. While not too many details were given, what we know is, thanks to “Project Cheesecake,” a user on XDA by the name of Stevendeb25 managed to pull an update for the Atrix from Orange UK and found an unlock capable bootloader. Yeah, pretty big news.
This now means that with a fully unlocked bootloader, Atrix users in the UK will finally be able to enjoy custom ROMs like Cyanogen Mod or MIUI and all the beautiful Android goodness they bring along with them. Bye, bye Motoblur!
Still no word or instructions on how to apply this update to your Atrix but we’ll keep you posted.

I had +1’d this just to saying bye bye moto blur
The ATT Atrix has had a bootloader unlock method for three weeks now.
This is for the Bell and International versions
oh, didn’t realize unlocking the bootloader would have been different for each carrier. ROMs yes but didn’t think bootloaders too.
Nice! Suck it Moto!
Finally, I really don’t understand why they insist on locking the bootloaders!
That made me get a SGS II instead of the Atrix..
