At this point, the HTC HD2 is nothing short of legendary. The phone originally launched with Windows Mobile 6.5 way back in 2009, but it's super high-end specs (including the first 4.3-inch touchscreen) and easy hack-ability have made it the host to more Windows and Android mods than you can shake a stylus at. After a CM9 port, you'll soon be able to rock Ice Cream Sandwich on your gigantic proto-superphone along with HTC Sense 4.0 - just as nature intended.
The custom ROM comes from (where else?) a team of developers on XDA, who call their project BlackOut ICS Primo. If it weren't for the Windows button and the EDGE logos, you'd swear this was an official (if somewhat belated) update. The team has only released a preview of the software, based on the HTC One V ROM thanks to their identical resolutions, but they say they're working hard to bring it to fruition.
Currently some pretty crucial components are non-functional, including the camera, SD card storage, data, WiFi and audio. When it's complete the ROM will only work with T-Mobile. Hey, this is bringing Ice Cream Sandwich and Sense 4.0 to hardware that's nearly three years old and designed for a now-defunct OS - it's no walk in the park. Good luck to you, Team Blackout. Yours is a noble task.
