OFFICIAL 2.1 UPDATE FROM SPRINT(DE03)

Jus an FYI, I'm alittle late to the join, but after 2 days of trying to flash 2.1 and always getting stuck at the Debug Setup Connection the only advice I found which worked was to open msconfig and disable everything from startup with the exception of the necessary Windows files. After that everything flashed perfectly. Had a harder time getting the phone to get connected, but after pulling the battery one time and reconnecting it worked perfectly. Hope it helps with those trying to update or install live windows.
