It seems like the iPhone just got some serious competition from the Windows Mobile camp, as pictures of what is currently known as the HTC Touch HD have appeared online at multiple Websites and for once, the pictures actually show quite a lot of details.

The device itself is unusually clutter free for a Windows Mobile device, as it only has four buttons on the front facia (which consists of a call and end call button, as well as a home and back button), although all of them are flush to the front of the device and are most likely touch sensitive buttons.

The screen size hasn't been confirmed as yet, but it's guesstimated to be over 3 inches, but the resolution has been confirmed as WVGA which is 800x480 pixels, which will give the Sony Ericsson X1 a run for its money. The device itself measures 115x62.8x12mm (HxWxD) and that makes it only slightly larger than an iPhone, which should appeal to a lot of people.

Other features include a 528MHz Qualcomm processor, 512MB of ROM and 288MB of RAM, GPS, HSDPA, a 5Megapixel camera, although without a flash, a front-mounted camera for video calls, a microSD card slot and a top-mounted 3.5mm audio jack.

It will be runNing one or another version of HTC's TouchFLO 3D UI on top of Windows Mobile 6.1 and it's expected to hit retail as soon as this Christmas if we're lucky, for a yet unknown price.
