This weekend, the folks at XDA got their hands on a new Windows Phone 7 leaked ROM, which supposedly comes from a device codenamed the HTC Mondrian on Cingular USA. This is a bit strange since Cingular has been long gone and it has been At&t Mobility since 2007. There’s a long thread over at XDA with some of the top chefs working on it.
The above image was extracted from oemavatar.cab. This could either be a generic image being used as a placeholder, or it could actually be the Mondrian, which has been referenced throughout the ROM. In addition to that image, they believe it has a 4.3″ WVGA display from Optrex and a 1.3GHz QSD8650A/B Snapdragon (the new 45nm) processor.
