The Motorola Atrix may not be quite ready for release just yet, but that hasn’t stopped those who have their hands on one from already achieving root access.
Thanks to several users over in the XDA forums, the day you go buy your shiny new Atrix 4G is the day you should be able to root your phone, side-load apps, and tether to you heart’s content. Unfortunately, the boot loader is indeed signed, so no custom ROMs for now. With all things considered, especially the current availability of the Atrix, things are headed in the right direction. For more info on the process, and to check in on progress being made, check out the [How To] Root, Sideload & Tether Your Atrix (Bootloader Signed) thread now.
