It appears the ill-fated Hottest Girls application isn't the only thing making new iPhone users sweat.

Apple has yet to respond to the claims.

French site Le Journal du Geek featured a photo of what appears to be a scorched Apple iPhone 3G S, which the site says overheated and turned the white casing pink, or light brown from the heat.

Another French site, Nowhere Else also posted images of Apple iPhone 3G S devices discolored by overheating.

Domestic users are also feeling the heat. One of the forums on Apple's Apple Discussion site indicates that a host of users' iPhones are overheating. One user said a friend's Apple iPhone 3G S "got extremely hot. He almost put it into the fridge."

The early blame seems to fall on games and GPS, resource-intensive applications that are pumping up the battery until it gets too hot to handle and eventually overheats.

Even over on PC World, Melissa J. Perenson wrote that her Apple iPhone 3G S "became very hot. Very, very hot -- not just on the back, but the entire length of the front face, too." At the time, she was using a game and then the Web browser over a Wi-Fi connection with the device plugged in. "Toasty doesn't even describe how surprisingly hot it got. It was too hot to even put the phone against my face."

One commenter shared this tale: "I had my iPhone under my pillow playing music through the head phones for a nap; I awoke with a sharp pain on my left arm under the pillow. I had been burned decently from the iPhone getting so hot. The phone seems to function fine though."

While another offered this advice to users of overheating iPhone 3G S smartphones: "Throw out your microwave -- simply drop your iPhone on the plate instead."
