When the Android 3.1 update was announced for the 3G enabled Motorola Xoom, some WiFi only Xoom owners were a little upset at having to wait, even if only a little bit. However, some actually received the update that day despite Motorola stating it would be happening in the coming weeks. And now, Motorola has announced that the Android 3.1 update is slowly being rolled out in phases. If you already received it -- awesome (and snag the manual download location)! If not, sit tight and take satisfaction in knowing it's coming sooner rather than later.
