The HTC HD2 was released in late-2009, and was among the first few phones in the world back then to run on a blazingly fast 1GHz Snapdragon processor. As good as the HD2 specs were, its OS – Windows Mobile 6.5 – was a major disappointment.

However, since the HD2 went on sale, the awesome developer community behind the handset has managed to get every mobile OS to run on the handset, including Android 2.2/2.3, WP7 NoDo/Mango, MeeGo and Maemo.

Now, adding to the above list is the latest release of Android – Ice Cream Sandwich. Thanks to developer tytung, HD2 owners can enjoy some Ice Cream Sandwich goodness on their phone. The ROM in itself is a port from the Nexus One’s ICS AOSP build, and thankfully most of the core functionality works with the build.Wi-Fi, 3G, Touchscreen, Bluetooth, GPS, Calls, some sensors, and audio work flawlessly, but USB Mass storage and Camera do not work. Sadly, H/W acceleration, which is one of the most important changes brought about by Google in ICS, does not work as well.

The good news is that the developer is hard at work on fixing these issues, and its just a matter of time before a stable ICS AOSP build comes out for the HD2. Interested HD2 owners can head over to this thread over at XDA forums for more information, installation steps and download links.
