Need a flash light quick. Set the register so the flash comes on by default when you push the camera button.

Edit the registry HKLM/software/camera Change value Flash to 1.

Now when you push and hold the camera button on the side of the phone with the lid closed the flash will show you the way.

Nice trick. I've used the flash as a flashlight on a few cell phones, including this one, before. It is fun!

There is also a program called "pocket light" that works great also lets you send morse with the light, you can find the link at the PN-820 wiki under programs that work.
