Making good on their word, Motorola has just let everyone know that the first Motorola XOOM update is going to start rolling out tonight in phases. While Adobe Flash was missing at launch, Motorola did say it was coming later. No, you're not getting Flash tonight but this update will help that process along when it comes time. If you're rooted and what not, you'll likely want to hold off just a little bit so that the file can be looked at but, if that's not a concern for then by all means-- have at it should you see the update pop up tonight for you.

*Update* Official word comes to us via the Motorola forums: "If you have unlocked/rooted your Motorola XOOM, you must restore it to the standard software load and relock your device to receive the notification."
