Last month, European Wi-Fi Xooms received the latest version of Honeycomb, and now it's coming to its more mobile 3G-bearing sibling. The update includes a new apps scaling feature so that apps designed for the smaller screen display better on larger devices, along with support for SD card expansion. According to forum posts by a Motorola support representative, the update is rolling out now to Austria, Croatia, Denmark, France, Germany (both retail and T-Mobile versions), Greece, Hungary, Ireland, Italy, Netherlands, Norway, Poland, Romania, Spain, Sweden, Switzerland, and the UK. Confusingly, the forum posts direct users towards the My Xoom support pages for more information, but nothing relevant is posted there.
The update's likely to be over-the-air, so it's worth checking your Settings if you haven't received the notification already. It's been a long wait for the Honeycomb early-adopters — 3.2 was slated in Europe for an October release and US 3G devices received it back in August — and there's no sign of an Ice Cream Sandwich update on the horizon.
