I've read through the forums, over-clocking 101, root'n for newbs, etc etc and I've gone through ROM after ROM, kernel after kernel and it doesn't seem to matter what i do, my phone is always hot. Just plugged in it's 100 degrees. I'm currently running chevy's low voltage 800 Mhz kernel and I have is scaled down to 550, and just now playing angry birds it's at 130 degrees.

Do I just have a dud phone here? If I return it to stock, non-rooted, what is the best way for me to prove that my phone is constantly hot to get it replaced?
