Well, Eric Lin did tell us that HTC is planning on being involved with Windows Phone 7 from "day one" and it looks as if he wasn't fibbing.

Two handsets have turned up in a XML database file from HTC's MMS specs page and both are running Microsoft Internet Explorer Mobile 7 - the browser of Windows Phone 7.

The two handsets in question - the HTC Mondrian, which we have tipped in the past to be a Windows Phone 7 launch handset, and the HTC Mozart.

There's no detailed specs on offer from the XML files, other than we're looking at a couple of non-physical QWERTY handsets with WVGA screens and Bluetooth connectivity (with A2DP).

Previously though, we reported on leaked details of the Mondrian which suggested that it will have a 4.3-inch screen running on a Qualcomm QSD8650A/B 1.3GHz Snapdragon processor that supports both GSM and CDMA.

The previous leak also hinted at  a camera with HD capabilities, at least 5 megapixels and a digital compass.

We're also expecting to see HTC launch the Windows Phone 7 boasting HTC Gold around November time.

So, it looks like the HTC and Microsoft partnership is back together after a number of high profile HTC Android releases. HTC has a huge, loyal fanbase and it will be fascinating to see if its Windows Phone 7 devices will be enough to get Microsoft back on par with Apple and Google when it comes to mobile operating systems.
