Bing Vision is limited to just scanning Microsoft Tags and QRCodes outside the US, which is a major limitation when it is such a sexy feature of the Mango update.
1800PocketPC has posted this simple guide to enable the feature internationally. It simply required setting your Browser and Search language to English (US) by:
- Click on Settings
- Scroll down to region + language and select that
- Scroll down to Browser and Search language
- From the list choose English( United States )
- Hit the back button twice
The main limitation of this is that results for products will be for US stores, but then it did not work at all before, so it is not a major issue.
