XDA Developer, boyppc has lot of good Android builds for HTC HD2. They are CM7 Sense.s, CM7 HoneyComB, MIUI, Desire HD and HTC Sense 2.1 & 3.0 builds. Most of them are updated to the latest Android 2.3.4 Gingerbread except HTC builds. I took Ginger 2.3.4 HoneyComB as testing. And Google Talk with video and voice chats is working. Be sure to check out XDA website for other builds.
