I leave my 3GS iPhone in the console of my truck that sits in the sun in over 100F Texas heat (so temp inside truck pushes past 110F) and my iPhone always mostly works- some times the cell reception sucks when its "ouch it hurts to touch it" hot. I have never seen that temperature screen.
You probably need a new battery already. Heat severely impacts the usable lifetime of lithium-Ion batteries, like those in phones and most portable devices.
