no, i had the right rom. my computer wouldnt activesync, and the instructions said to make sure it could. i figured, either it will see it and work, or it wont see it and it wont work. so i hit next, and it asked if id like to upgrade? i said yes, and it said it could take 10 minutes. 5 seconds later, my bl was updated, and 5 minutes later i had radio and rom installed. so i am now running dcd 3.1.2 radio 3.39.10
moral of the story, computers are stupid.
