A handy Russian hacker succeeded in providing the HTC HD2 with Windows Phone 7 Series. That's quite smart if you realise that the HD2 is not at all suited to run WP7S and that WP7S is not even available yet!
There's proof too, but not in the form of an image. A video will definitely prove this succesful 'port'.
There is hope for HTC HD2 owners. The result does not yet look so 'snappy' as we saw before, which according to the source is mainly because the graphic drivers do not function yet.
In all it looks reasonably impressive, especially looking at the fact that WP7S is not yet finished, and that the HD2 is not at all suitable for this new operating system. Below some more recordings of WP7S on the HD2.
