So...I e-mailed HTC tech about the keyboard backlight...

So, I finally got tired of searching for a way to hack or reg edit the keyboard backlight. I decided to e-mail HTC tech support and asked them if there is a work around with registry and/or a DLL hack...here is the response:

Hello Scott,

Thank you for your inquiry

I know how frustrating it can be to not have your device function the way it should. Unfortunately the keyboard backlight on the Touch Pro is hardware controlled. You may be able to adjust the backlight settings to prolong the keyboard backlight time by going to Start >> Settings >> System >> Power >> Advanced and adjusting the backlight timer to your preferred time.

So...that sucks, but also sounds like they may not know what they're talking about. Who knows, but this still sucks.
