Yes, you heard it right! It’s Android on HTC HD2. A group of developers who call themselves HTC Linux have managed to port Android 2.1 on HTC HD2 smartphone. HTC HD2 runs on Windows Mobile so it wasn’t easier to run Android over it. However, “HTC Linux” team managed to change the code and port Android to HD2.

The concept is very much same as for iDroid (Android on iPhone port). Like iPhone, HD2 also becomes a dual boot device and you can choose any of the available OS at the start.

You can get more details about it at XDA-Forums Thread.
