HTC unveils their first Windows Phone 7 handset: The T-Mobile HD7

Aaand the onslaught of Windows Phone 7 handsets begins. Right as Microsoft’s own Windows Phone 7 event is scheduled to begin, HTC has pulled back the curtains on their first WP7-powered handset: The T-Mobile HD7

Leak, after leak, after leak, the HD7 is about as secret as a ruined surprise party. You know it’s coming, your friends know you know, but everyone still plays along for the sake of good fun.

As the name implies, the HD7 is designed in the same vein as the Windows Mobile 6.5- powered HD2. That’s sort of funny, given that the HD2 was pretty much the last major 6.5 handset, and was the source of a mighty uproar when HD2 owners were told that they definitely would not be getting upgraded to Windows Phone 7.

In fact, the HD7 is really similar to the HD2. They’ve both got a 1Ghz Snapdragon CPU. They’ve both got that gigantic 4.3″ WVGA (480×800) display on the front. They’ve both got 802.11b/g/n WiFi, and a 5 megapixel autofocus camera with LED flash. Outside of the much welcome addition of a 16 gigabyte chunk of internal memory in the HD7 and the operating system differences, the two models are about as close as it gets.

While the rumor mill (which has gotten just about everything else HD7-related right so far) pins it at $200 post contract, T-Mobile is keeping the price under wraps for now. They will say that the handset should launch around mid-November, which matches up damn near perfectly with the November 17th launch date we heard way back in July.

What do you think: is the first WP7 handset off the block tugging at your heart wallet-strings?
