Nate - I'm wondering the exact name of the battery widget you're using - that displays the temperature as well as power left.
I've seen it come up a few times but I'm having trouble finding it in the market.
It might be because it's a paid one? (My carrier is currently blocking paid apps).
Cheers
the exact name is "BatteryLife" with no spaces. If you type that in it will be the first app...it's free!
