Guys, here’s a hot one! XDA Developers have already dumped Windows Phone 7 build 220.127.116.1177. This is the starting poing for all work in the direction of porting to devices and making custom ROMs. It’s a long road ahead though… and in the lack of an actual ROM for an actual device might be close to impossible, but it can offer precious information about the platform and how it’s built and working.
The build comes from the Windows Phone 7 Emulator for PC. ROM image build date is March 2, 2010.
