There have been reports that the new iPhone 3GS is too hot to handle, the super-fast processor's temperature is so very warm, owners claim it can hurt.
Photos of white iPhone 3GS posted in forums show heat scorch marks, like the kind you see when the iron stays too long on a shirt, except this one looks reddish pink.
The Journal de Geek in France shows a photo of a hot pink mark in the shape of a battery, with the metaphorical question "Isolated case or what?.

Melissa J. Perenson reported that her Apple iPhone 3GS "became very hot.
Very, very hot -- not just on the back, but the entire length of the
front face, too." While she was playing the Oregon Trail game and surfing the web
browser via a Wi-Fi connection. "Toasty doesn't even describe
how surprisingly hot it got. It was too hot to even put the phone
against my face."
A MacNN staffer has encountered the "hot"problem independently, with discoloration noticeable on the back of a white 32GB unit.
Aaron Vronko of Rapid Repair, Apple iPhone repair specialist, told us that the overheating is likely due to faulty battery
cells which could spur a recall.
"The safety concerns of this lithium ion battery in the Phone 3GS is less likely to pose as great a risk of fire or danger as with larger cells in a laptop battery."
If you notice this problem, if your iPhone 3GS is not too hot to touch, shut off the iPhone immediately. Charging or using current will exacerbate the reaction. (There is no way to turn off an iPhone without touching it with bare skin or using a specialized stylus like the Pogo.)
Vronko advised "Don't leave your iPhone in very hot places such as
the car in the summer where it can get as hot as 120 degrees which will
degrade the battery life."
If you expose the iPhone battery to
extreme temperatures, regularly, your battery could need to be replaced
in a few months. The same is true for very cold weather, below 40
degrees F, it will degrade battery life.
Apple recalled the iBook G4 and PowerBook G4 notebooks because Sony cells in batteries could cause explosions.

problem might blow up in Apple's face--literally--if someone's iPhone 3GS
battery explodes."
