Recover N900 lock code with recoverlock script
Alexander Kozhevnikov's recoverlock is a small shell script to automate the recovery of the N900 lock code. For all those times when someone sells you a used N900 and forgets to reset the lock code to default, and the like.
Just install it, run the command 'recoverlock' in X-Terminal, wait until it finishes doing its thing, and you'll have your lock code. I recommend you uninstall it afterwords, so that you don't have the command sitting around on your N900 waiting for someone or something else to notice and misuse it.
