Earlier this month we showed you a glimpse at the progress being made to get Android working on the HTC HD2. It was far from ready, to say the least. Well, since then, a huge leap has been made at xda-developers. In this video, you can see that the latest build works almost entirely: cellular data and WiFi is working, the navigation is smooth, and it even makes calls (though the speaker doesn’t yet work). If you’ve got an HD2, this is super easy to try and you can always go back to Windows Mobile by soft-resetting. Just load the files onto your storage card, run Haret.exe, and wait some time.
