We’ve been covering the efforts to get WP7 onto the HTC HD2 for some time now, but your patience has paid off, as the hack has been completed! The release is imminent, and while it’s not a fully functional version, much of what makes WP7 great is there. The problems arise from a previously reported issue whereby all cloud services are unusable. You can still email, make phonecalls and the like, but Windows Live functions like Live Tiles and Marketplace won’t work.
However, we’ve heard rumor that this security protocol has been cracked, so maybe we’ll see these features soon.
