Getting Android running smoothly on the HTC HD2 has been a reasonably long project, but the xda-developers teams working on the port are getting close to perfect releases. There are now two almost complete builds available for download, one offering Android 2.2 Froyo for the HD2, and the other taken from an HTC Desire and promising Android 2.1 with HTC's Sense UI and accompanying widgets.

As you might expect, neither build is perfect yet. Audio seems to be the biggest hurdle right now, with in-call sound not playing ball properly. The Froyo ROM's 3G data also seems to have issues, though they're apparently not present on the Eclair ROM.
