Backlit screen when using the phone

[smoerbe]

Is there a way to turn the screen off while on the phone? My first reason is to conserve battery life. However, I also notice a very high pitch whine when the screen is backlit and the phone is to my ear.

When you make or receive a call, push the blue/shifty button beside the Z (alt key I guess) and then hit the P button. It will at least dim it and save some battery life.

I found a product called Treogaurd from www.geakware.com. You can download a trial first, but it only cost $9. It lets you create settings that will turn off the screen during a call. It works great, I used it for a day and shelled out the $9.
