Sure, AT&T set a self-imposed deadline for HSUPA support on the Atrix 4G, but it's waited until the last possible moment to turn in the completed assignment. Soon after hearing that a hack can flip the upload switch to "speedy", we learned that beta testers have been handed an over-the-air update to version 4.1.83. Motorola's site lists the changelog and vaguely mentions that the update brings "increased speed at which data can travel on the network." While such a statement implies the update will crank the HSUPA knob to 11, reports from testers are backing up the theory left, right, and center. Aside from the elephant in the room, the new update should bump the Atrix 4G to Android 2.2.2 and bring improvements to Wi-Fi, Skype, and email, along with a fix for the occasional frozen display bug. Of course without AT&T making this update widespread, and with only three days left in the month, it looks like we might have to dock points for tardiness.
