A few days ago we noticed HTC Watch has shown up in Marketplace, and then, while anyone could download it, it was not really functional.
HTC has however updated their Video on Demand app, which for most readers means the device will give an un-recognized error and refuse to do anything, include even showing trailers.
For some other user it means the app is now fully functional, meaning they are able to view trailers and rent and purchase movies.
Hopefully the service will eventually roll out to all HTC handsets but I suspect regional restrictions will remain in the vast majority of countries.
Thanks DJDurance for the tip.
