what's the deal with weather panel? What features are you using on it, I guess what I'm asking is what is your main purpose for using the app?
I would suggest as mentioned, to get the keyboard light program. I used that application and never have my keyboard illuminated.. saves greatly on battery.
If you're using Weather Panel to just get the forecast for your area you and you have text messaging you could always go to
