I tried the SIM tray trick, and it helped slightly. Still gets pretty dang hot, but not as bad as before. Hotter than my 3G's ever were.

EDIT:SIM trick= eject and reinsert SIM tray. Factory installation is apparently not the best.
 
If I am using my phone anywhere but inside if I have gps and phone working it heats to the point the back light wont come on and feels way too hot.
