Both the HTC Mondrian and HTC Mozart, both confirmed to be running Windows Phone 7 by the browser ID, which is listed as “Microsoft Internet Explorer Mobile 7”,
The HTC Mondrian’s XML is here and the HTC Mozart’s is here.
The MMS info does not reveal too much, except that both devices predictably have WVGA screens and also that they are both slates without keyboards. The XML also references supported Bluetooth profiles, and we can see support for A2DP, Object push and of course the various hands-free profiles. At least we know, unlike the iPhone, Windows Phone 7 will support A2DP and MMS at launch
