The HTC HD2 (also known as the HTC T8585, HTC T9193 and HTC Leo),[4] is a smartphone belonging to the HTC Touch family, manufactured by HTC and running the Windows Mobile 6.5 operating system. The phone was designed and manufactured by HTC, and was released in Europe in November 2009, and in December 2009 in Hong Kong. In some other regions, including North America, it was released in March 2010.[5][6]The phone is the successor of the HTC Touch HD, and is succeeded by the HTC HD7.

It is the first smartphone with a 4.3-inch touchscreen, the first Windows Mobile 6.5 phone with a multitouch capacitive screen and HTC Sense, and the second smartphone with a Qualcomm Snapdragon CPU (the first being the Toshiba TG01).[7][8]The Snapdragon CPU is clocked at 1024 MHz, but automatically underclocks itself to 553 MHz if extra processing power is not needed.[9]Tweaks have been made however, to clock the processor at a constant of 998 MHz.
The HD2 is fitted with a Asahi Kasei AK8976A magnetometer. [10]The magnetometer is used for applications such as the pre-loaded digital compass.
Rumours of the HTC HD2 began appearing in September 2009. It was codenamed Leo, although a decal on the back cover conflictingly identified it as the Pro.Three [11](which indicates it may have been intended as a bridge between the HTC Touch Pro and HTC Touch), and the About info in Bluetooth as the HD2. The specifications sheet released turned out to be true when the HD2 was launched, with the exception of the listed 320MB of RAM, compared to the final 576MB (448MB available to user) of RAM.
When launched in the UK, Vodafone quickly sold all of its stock and developed a backlog of orders, and O2 delayed putting the HD2 on its website so that it could fulfil all orders.[12] Similarly, in the US, the HTC HD2 sold out in most T-Mobile stores within 4 hours and T-Mobile struggled to keep it in stock for several weeks.[13][14]
Certain T-Mobile locations ran a promotion that stated that iPhone users who traded in their handsets could get anywhere from $100 to $350 dollars off the HD2.[15]
The HD2 was originally slated, according to HTC and popular belief[16] to be upgraded to Windows Phone 7 (then known as Windows Mobile 7). Microsoft rejected it and other Windows Mobile devices[17] however due to it not being compliant to the company's hardware requirements for smartphones running Windows Phone 7 - including a lack of dedicated two-way camera button, and five hardware buttons on front as compared to three supported. Developers have however successfully ported Windows Phone 7 to the HD2. Microsoft has surprisingly expressed tacit and subtle approval of such ports, nearing the release of Mango for native Windows Phone 7 devices.[18]
Unlike its sibling, the HD Mini, the HD2 has not received an official upgrade to Windows Mobile 6.5.3, the latest stable release of Windows Mobile (the HD2 natively runs 6.5.0). However, several developers at xda-developers have prepared unofficial 6.5.3 and 6.5.5 (the latter being the last unstable release of Windows Mobile) ROMs for the HD2.
HTC officially sells an optional capacitive stylus pen for the HD2 to aid navigation through the interface.[19] Some Windows Mobile applications were designed to be used with a stylus, rather than finger-touch, and still need a stylus pen to be used effectively.
The HD2 is sold with a brown leather slip-case with a velvet interior in certain countries. [20]
An extended battery is available also officially from HTC. The official unit comes with a metal kickstand.[21]
Android (versions 2.2 Froyo, 2.3 Gingerbread, and later 4.0 Ice Cream Sandwich), Ubuntu, MeeGo and Windows Phone 7 have been unofficially ported to the HD2.[22][23][24] In addition, many customised versions of Windows Mobile are available for the device, with version ranged from 6.1[25], 6.5[26], 6.5.3[27] to 6.5.5[28]. Users who are not satisfied with the existing functionality of the device, or who are just curious, can mod the device to make it more usable and useful.[29]
In early October 2010, a video was released that appeared to show a HD2 booting into Windows Phone 7 by way of Russian developer Cotulla's MAGLDR tool (a bootloader), which was initially created to allow the booting of Android from the device's NAND flash.[30] As of January 13th 2011, MAGLDR and a WP7 ROM are publicly available. Windows Phone Genuine checks prevent access to Windows Live services.[31][32] A solution to this problem has been found, though the legality of the activation is still not fully known, and is frowned heavily upon by Microsoft. [33] Windows Phone 7 Mango RTM (Release To Manufacturers) was ported to the HD2 in August 2011[34], a month after ROM developers at xda-developers made successful an attempt to run a beta version on the device.
The HTC HD2 has also been modified to run Windows 95,[35] Windows 98 and Windows XP,[36] through a ROM image on QEMU Puppy, although networking does not function on Windows 95 and Windows 98 as of 2010.
First PlayStation Emulator for Windows CE, a PlayStation 1 emulator for Windows CE devices, was ported to the HD2 in December 2009, a few months after the initial release of the HD2.[37]
