(Update on Monday: video how-to) Motorola's Atrix 4G has already been rooted and given full control even just two days ahead of its early launch. Custom ROM developers designgears and Getaphixx together granted full access to the Android 2.2 firmware on Friday. The move takes away AT&T's restriction on installing non-Market apps and also lets users remove the unwanted carrier apps that are normally forced on.
The hack also enables more control over the OS than what Google allows, including backups and modifying core elements.
As with all rooting, the technique by its nature makes Android more vulnerable to security risks than in its normal configuration. It also doesn't have the blessings of AT&T or Motorola and breaks the warranty while installed. It's not clear if designgears has a factory stock firmware to bring it back. [viaBriefMobile]
