Taiwanese mobile phone maker HTC Corporation is expected to be among the first vendors to come to the market with handsets running under Microsoft's new Windows Phone 7 operating system, and the long rumored HTC HD7 is one of the first such devices in the company's lineup.

Originally leaked into the wild under the name of HTC HD3, this Windows Phone 7 device has just received the necessary approvals from the Global Certification Forum, and also emerged in what seems to be the first photo showing it with T-Mobile branding all over it.

Most of the specifications HD7 comes to the market with were already brought to light, but little is known so far on the mobile phone's actual market availability.

The device should come with quad band GSM / GPRS / EDGE and with dual and UMTS / HSDPA / HSUPA at 900 / 2100 MHz connectivity options on board, as the GCF approval shows (via the unwired).

Rumor has it that HD7 should land on the market in Europe via various carriers in more than one country, and it appears that T-Mobile USA is also set to launch the new mobile phone in the near future, at least this is what the photo that emerged at TmoNews suggests.

Interestingly enough, it appears that the US-bound version of the new mobile phone should land on shelves with enhanced hardware specs.

Thus, US users would have 16GB of internal memory at their disposal with the new device, unlike European users, who would enjoy only 8GB of memory.

The specs list for the US version also includes 576MB of RAM, as well as support for HSPA 7.2Mbps (although some of the last devices at T-Mobile support faster speeds).

Other specs of the device would include a 4.3-inch touchscreen display, a 5-megapixel photo snapper with dual LED flash, Wi-Fi connectivity, GPS receiver, and more.

On top of that, the news site says that the price tag of T-Mobile's HTC HD7 has been unveiled too, and that it was set at $199.99 after the signing of a 2-year agreement.

For what it's worth, there are great chances that the HTC HD7 Windows Phone 7 device would be unveiled officially as soon as tomorrow, since Microsoft should launch the new mobile OS then, which means that more on it should become available soon.
