Gingerbread (Android 2.3) is finally available on the Motorola Atrix 4G!  Updates and changes since the original launch include a new version of Motorola's Applications Platform, the ability to sideload applications and uninstall AT&T-branded software, battery life improvements, and enhancements to select apps.  Outside of the changes, overall performance is significantly better - the lag that plagued the Atrix at launch is completely gone, putting it on par with other Motorola handsets like the PHOTON 4G, DROID 3, DROID X2.  With the Gingerbread update, the Motorola Atrix 4G rises to become the best Android handset on AT&T.
