Bug Description
If you enable pin unlock, then repeatedly enter the incorrect pin, eventually you'll get a message stating that the phone cannot be unlocked for 5 minutes. However, this restriction can be trivially bypassed by simply rebooting the phone (which takes less than 5 minutes :-)

I think this was discussed and ACKed by security, the time needed to reboot is enough to prevent any real bruteforcing of the password.
