from my experience, the heating subsided after a couple of days of use or you'll get used to it. don't bother sending your unit to be fixed cause they will find nothing (ask me how i know). the phone will get very hot when using the camera, especially in pro mod, and in video mod at 60fps hd i got a couple of warnings after 6-10 minutes of filming. on the bright side, its good for keeping a cup of tea warm... its good if you need a hand warmer... etc etc... its a shame imho.
