Can I have another scenario? User is waiting for important call, phone in his pocket, expecting it to ring. Firmware crashes, reboots... and asks for a PIN. When the important call comes, phone is not available... as it is waiting for PIN... I believe even pretty old Nokia's did cache the PIN so .. exactly this did not happen.
