Computerworld posted more details about Microsoft's revamped Windows Phone 7 OS

Coders at XDA-Developers.com hacked the ROM for an un-announced HTC smartphone, called Mondrian, with a Windows Phone 7 software build, though it's still referred to as "Windows Mobile 7". The Mondrian may be destined for AT&T because there is likely outdated reference to the wireless carrier's previous name: Cingular.

Microsoft in April released for developers a new emulator for Windows Phone, based on the latest released build of the underlying operating system.
