@Motorola_CA: Motorola XOOM owners: Your Android 3.1 update is here! Have questions? Call customer support at 1-800-461-4575.
We'll go ahead and assume that like most other updates of this proportion, Motorola will be rolling it out gradually rather than all at once. Nevertheless, you can begin feverishly checking for updates, as it is certainly on its way. Shout out below when you finally receive it, and be sure to let us know if you encounter any problems during the process.
