Nothing like a little software update to get the weekend started right... right? Just days after Samsung shipped the first consumer units of its Galaxy Tab 10.1 (you can find our review here), the Android 3.1 update that first struck Motorola's Xoom is now gracing the Limited Edition models that were handed out at Google I/O 2011. We've confirmed here at Engadget HQ that the update is indeed percolating, with Americans needing to simply register with Samsung (select "UK" in the options list, it's cool) and proceed to the Software Update within the Settings pane. If you've applied the update, let us know how things went in comments below; if you ran into any issues, give those More Coverage links a look. Either way: lucky!
