Android 4.0 Ice Cream Sandwich’s source code was handed over to the Android Open Source Project (AOSP) a few days ago and we are seeing first attempts from the developers community to port Ice Cream Sandwich to some of the most powerful and popular smartphones. We’ve already covered how you can install Ice Sandwich on Galaxy S II, and in this is post, we’ll be talking about Ice Cream Sandwich for the old yet still mighty HTC HD2 “Leo”.

The HD2 was HTC’s last Windows Mobile-based phone when it released in late 2009. It has, or really had, an active hacking community that made the phone do various amazing things like run Android, Windows Phone 7 and even Ubuntu-Linux. Today, we saw an all-new hack released for the HD2: it’s called USB Host and it allows your HD2 to, well, play as host device instead of client in order to connect to different USB peripherals.

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!

It’s nothing new that the much-loved HTC HD2 can be hacked in order to install either Android or Windows Phone 7, but how about dual-booting?

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.

The day has come, dear readers! Microsoft, at their Windows Phone 7 launch event, has officially announced all the things we’ve wanted to know about WP7 since its original public unveiling in Barcelona.

Officially speaking, HTC’s HD2 will not be getting a Windows Phone 7 upgrade. All because it doesn’t comply with WP7’s hardware specifications. And what hardware specs, you might ask? Not having three buttons! Yes, HD2 won’t get WP7 all because it has two extra buttons despite the fact that it meets all other specifications.

Full specification sheet, along with real life pictures of HTC HD7 / HD3 has been leaked into the wild. For those of you who don’t know, HTC HD7 / HD3 is a Windows Phone 7 device and is the highly anticipated successor to last year’s HTC HD2 (a Windows Mobile 6.5.x Phone).

HTC announced earlier that they have plans for launching a Windows Phone 7 handset but they never mentioned or revealed any price, specs or estimated release date for the said device. But now, a leaked inventory document of German cellular network O2 has revealed an upcoming Windows Phone 7 device by HTC, dubbed as the “HD7” which is likely going to be successor of the much popular Windows Mobile handset HTC HD2.

Well its here finally! I got my iPhone 4 shipped here the other day and needless to say, the experience so far has been nothing short of spectacular. It’s a factory unlocked version which I got from UK. What this means is that I can use it with any carrier I like, unlike the US version which is tied to AT&T contract.

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.

The KIN phone has a really neat looking UI which appeals to quite a a lot of teens out there. Unfortunately though, the KIN didn’t get all the attention which it should have got. And now without having to buy a KIN phone, you can get that same interface on your Windows Mobile based phone as a theme using the KIN Launcher.

Android 2.2 aka Froyo is without a doubt the best version of Android OS that we have seen yet! The main thing which everyone was interested to find out was about the speed of the browser which Google claims to be the fastest amongst any of the mobile web browsers available on any platform today.

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).

One common misconception about Windows Mobile platform is that it lacks gaming abilities. You might want to reconsider this after you watch this video of PlayStation emulator (FPSECE) running some PlayStation titles like Tekken 3 and others on HTC HD2.

If you’re a die hard Windows Mobile fan and feel left out that why only iPhone and Android (soon) users gets all the glory of having their life in the cloud, then there’s good news for you all. The official Dropbox Client for Windows Phones (Windows Mobile 6.5.x, not Windows Phone 7) is now in the works.

If you have ever owned or use an HTC phone like HTC HD2 or HTC Desire with HTC Sense, you will know how great a job HTC has done in tightly integrating the phone with social networks like Facebook and Twitter. This is something that iPhone users have been missing even with three major iterations of the OS. But with iPhone OS 4, Apple is likely to change this all.

Wow! this is big! We all knew this was going to happen at some point, but not as soon as this. Apparently, some Russian folks have managed to port a “real” working ROM of Windows Phone 7 on the most popular Windows Mobile device – the HTC HD2. Tom Codon of HTCPedia has posted screenshots which shows off the device running an early build of Windows Phone OS 7.0.

HTC HD2 was a big success in the masses, majorly due to it’s multimedia features and it’s huge screen which provided the user with a rich multimedia experience, but unfortunately, it won’t get the Windows Phone 7 Series upgrade due to the strict hardware requirements of three buttons on the phone: Back, Windows and Search. The grail doesn’t end here, HTC’s CEO Peter Chou hinted on a phone which might probably be an HD3, and would hit the shelves in the end of this year – that’s exactly an year after HD2 shipped.
