I am in canada and have 'browser and search language' set to U.S English in order to activate bing vision, local scout etc.
I was hoping to activate the U.S. Bing search (vs the Bing version for Canada) by using the other settings ('system locale' and the 'region') but it didn't help. Bing.com in the USA does conversions and calculations and a few other things that the Canadian version doesn't. I have activated Bing U.S. on my computer but on the phone I couldn't (or at least it wouldn't do conversions/calculations).
Any ideas? Does Bing on WP7 in the USA do calculations or conversions?
