We’ve only seen Windows Phone 7 Mango running on the Asus prototype as well as on the HTC Trophy-like Mazaa with both the occasion of our Mango hands-on videos as well as Eldar Murtazin’s twelve-megapixel Windows Phone leak.

A video has surfaced on YouTube showing Windows Phone Mango running on the HTC HD7 — or is it the HD7S? You won’t see anything out of the ordinary in this video that you haven’t already known about the upcoming Windows Phone 7 platform refresh but oddly enough these build keep on popping up and we can’t help but wonder whether Microsoft is giving out HD7 smartphones as Mango developer devices — among others?
