After a long teleconference call, my iphone was blistering hot from extended use. Hot enough in fact, to damage the backing to the display. Looking at it it's clearly behind any image on the screen; guess I'm gonna visit a genius. I'm not sure what chip or component is under that spot. I'd be curious if anyone could ascertain what it may be. Here's two horrible images (sorry, only had my wife's 3g to take the pic) trying to show the burn spot. One is on a white field, the second is where I move the image to show it's the display itself and not some image being drawn.
