Like many, I thought that Motorola Xoom tablets would be getting the Android 3.1 update yesterday after it was announced at Google I/O. So I grabbed the one sitting on my desk and checked. Nothing.

The Xoom checks for system updates automatically every 12 hours, and the time hadn’t come due. So I forced it to check (tweaking the Date & Time to the future). Still nothing. I did it late last night. And early this morning. Nothing but bubkiss.

Turns out, the update will actually roll out through out the week, at least for Verizon tablets. Wi-Fi-only versions will get it sometime over the next several weeks. So if you’re a Moto Xoom owner who, like me, is wondering where the heck your update is, I hope this helps explain it.

Rarely have I salivated over something I knew so little about. Yesterday’s Honeycomb/3.1 announcement was a bit spare, but today, Motorola let loose a few more details:

  • Android Market movie rental support
  • Full support for the final release of Adobe Flash 10.2
  • Resizable widgets
  • USB support for peripherals and accessories
  • More Bluetooth support: Compatible with BT headsets in Google Talk vid chats, BT mouse and more shortcut keys via BT keyboard
  • Picture Transfer Protocol: Support for easier photo transfer to PCs (without drivers)

Are you one of the lucky few with your hands on the latest version of Honeycomb? What do you think so far? Go ahead, make me jealous by sharing your impressions in the comments.

Press release follows.
