Want to see Windows RT on a smartphone? We know you do, that’s why we’re fairly sure this latest news will excite you just as much as it does us. Windows RT has been ported to the HTC HD2 smartphone. Honest!

If you’ve only been following the movements of the smartphone industry during the last couple of years, you may not have heard of HTC’s HD2, but the old relic of a device – which first launched running another antiquated product in Windows Mobile 6.5 – has been modded to run the brand-new Windows Phone 8 ecosystem. That’s right, while Microsoft has given Windows Phone 7.x users the sad news that their beloved device won’t be upgradeable, the three year old handset designed by the Taiwanese maker has been pictured running Windows Phone 8.

The HTC HD2 might be an aging device but no one can deny the fact for what it is capable of running. Apart from the stock Windows Mobile 6.5 ROM it ships with, it can run Android and Windows Phone 7 as fluent as if both the OS’s were made for the HD2 itself. And now it can run the latest and greatest offering from Microsoft: Windows Phone 7 Mango!

Microsoft and HTC made it official that the HTC HD2 won’t be getting the Windows Phone 7 upgrade although the hardware supports it. But that didn’t stop the hacking community from dumping a Windows Phone 7 ROM on the HD2, yes you read that right! You can now boot Windows Phone 7 on your HD2 alongside Windows Mobile 6.5, Ubuntu, MeeGo, Android 2.2 Froyo or Android 2.3 Gingerbread.

Remember when we informed you last time about Android port which was in works for HTC HD2? Well guess what? Just like the Android port for iPhone 2G and iPhone 3G, it is now a reality on HD2 too, with Android 2.1 dual booting side by side with Ubuntu Linux “’Karmic Koala”, and Windows Mobile 6.5 with HTC Sense. Check out the video after the break.

We have previously seen different Windows phones like HTC Touch Pro2, Touch HD and Touch Diamond2 running Android OS through an emulation software named Haret. For different reasons, developers so far have not been able to do the same for HTC HD2 which by far is the most superior Windows phone available today.

The first American 4G phone, the HTC EVO 4G will hit the shelves on 4th of June for US $199 on a two year contract with Sprint. Since both the HTC HD2 and HTC EVO 4G shares almost same specs (hardware wise), the comparison between the two is evitable. One runs on Windows Mobile 6.5 (HTC HD2) while the other runs on Android 2.1 with HTC Sense (EVO 4G).

Just found this out on WinMo.nl website and thought it was worthy of a share. What you see here is a HTC HD2 running one of the early builds of Windows Phone 7 Series. According to the site, the build was working nice and smooth and it was shown running on HD2 to the audience in Barcelona present at MWC.

The official Windows Phone account on twitter has just posted some info about the possible Windows Phone OS 7.0 upgrade for HTC HD2. This is what they are saying at the moment.

A Chinese site by the name of QQ (QQ.com – English translated version) claims to have got hold of the specifications for the successor to HTC HD2. According to them, HTC HD3 will launch in November 2010 (exactly one year after HD2) and will be powered by Windows Mobile 7. Moreover, it will feature Qualcomm’s 1.5Ghz Snapdragon processor, a 4.5’’ HD display, HDMI port, support for 4G, WiFi and WIMAX, 8 megapixel camera with support for 720p HD recording, 16GB internal memory and 32GB external via microSD card.

Most of you who are either following me on twitter, or are subscribed to our facebook fanpage may already know that I bought Nexus One today and just to make it a bit different, I decided to unbox it side by side with another similarly spec’ed phone – the HTC HD2. Both Nexus One and HTC HD2 are powered by 1Ghz Snapdragon processor.

According to the latest Windows Mobile 7 findings by WMExperts, HTC Obsession could very well be the first Windows phone which will ship with Windows Mobile 7 come this fall. Microsoft may even show it off at the upcoming Mobile World Congress, where they are highly expected to unveil Windows Mobile 7 for the very first time.
