Rooting works through exploiting a security flaw in the phone. It would be downright irresponsible of Motorola not to fix that flaw (especially such a well documented one). You are buying a phone for what it can do out of the box, everything else has no guarantees... Also since sideloading still works Motorola didn't try to lock the phone down further they just fixed a security flaw.
Hey Guys and Gals
I'm in China right now and would like to get this update to see what it fixes. My atrix has been having some issues....
You will have to wait it out as they havent pushed it OTA quite yet. Or, you can try to check in your system update to see if its there. It didnt really fix anything for me because I didnt really have problems. But It did make things a lot smoother.
help me please. I want to download the new update for the atrix but I have to get rid of my gingerblur rom first. How do i do this? Do i really have to flash all the way back to stock and lose all my apps and stuff?
