With its large size 4.3-inches multi-touch screen, 1 Ghz Snapdragon processor and other amazing specs, HTC HD2, atleast in terms of hardware power has already bulldozed its contemporaries devices and is by now surely a big powerhouse in cellular world. We had tried to keep our readers updated during the entire course of its development phase through our various posts. Just to refresh your memory, HTC HD2 is powered by Microsoft’s newly released Windows Mobile 6.5 and is the first Windows phone to feature multi-touch support through HTC Sense (aka HTC TouchFLO 3D 2.5).

HTC HD2 is probably the most awaited Windows phone of this fall! The two major features which gives it an edge over its contemporary popular iPhone 3GS is the high resolution 4.3 inch 800 x 480 capacitive display, and a 5 megapixel auto-focus camera with flash. From all the video demos that we have seen so far, it looks like HTC has finally got a killer phone which is going to prove itself equal, if not better to iPhone 3GS.

HTC has finally, in an official announcement unveiled its long awaited high-end mobile device called HTC HD2 which was previously codenamed as Leo. HTC HD2 is powered by Microsoft’s newly released Windows Mobile 6.5 and will be the first Windows phone to feature multi-touch support through HTC Sense (aka HTC TouchFLO 3D 2.5) which up till now was only available on the company’s Android-based handsets like HTC Hero.

It looks like HTC HD2 will be arriving much sooner than we first thought it would. Engadget has been informed by a reliable source that UK carrier O2 will be launching HTC Leo on October 12 as HD2. O2 has it listed already on its intranet site with an October 12 launch date.

In the wake of the launch of Windows Mobile 6.5 based handsets on October 6, there are strong rumors that HTC is expected to launch its Qualcomm Snapdragon-based 1 GHZ CPU smartphone which is codenamed Leo in the last quarter of 2009 for a very competitive price of US $800.

Most of the secrets about the eagerly awaited HTC Leo saddled with Windows Mobile 6.5 are out already except for its release date and expected price. With its large size 4.3-inches multitouch screen and amazing specs, it looks like it is going to bulldoze all others devices in its path and is surely going to be a big hit.
