Word has it that an unbranded update for HTC's Windows Phone 7-powered 7 Mozart that's recently appeared over on xda-developers is imbued with Microsoft's fabled "NoDo" code -- that is, the good stuff with copy and paste support, performance improvements, and a CDMA stack (though that obviously doesn't matter for the Mozart folks). Results of the update procedure are still trickling in... so proceed with extreme caution, or just wait for users braver and crazier than yourself to report back on what kind of destruction the update process has wreaked on their beloved devices.
