I know I had to give my PIN when I bought it, but I did replace my Storm shortly thereafter and when I restored my backup and 3rd Party apps fro DM, it kept running (on a different PIN) and has been for 5 or 6 months now. I use it all the time. I guess if you could sell it, you have to offer a $ back deal if it wouldn't run. I'm not sure there's a big market for "used" software.
