I seem to remember there was a lot of talk around this whole topic around here somewhere--you may want to use google (the talk.maemo.org search has always returned less than worthless results for me) to search for threads that talk about this. I'm reasonably certain that even in the unlikely even that you found out where the lock code was, it would probably be scrambled and not useful to you--but I don't know that for a fact. Google to see what turns up.
