I havent bothered to read all the posts, but my N900 runs much hotter in 3G mode than 2G mode, I remeber from one of the first posts that you were just using the browser... If I download large files, it gets warm..so.. meh..As long as it isnt at like 55-60 degrees dont worry about it I say! Also, the temp in conky is batterytemp, replace the battery?
