We reported previously, that iPhone 3GS and 3G units were heating up when charging and with heavy use.  Apple let users know that there is a temperature warning via a support page.

Some believe the page is an acknowledgment of the overheating issues that spread like "wildfire" throughout the web with reports of pink scorch marks and toasty touches.

Like we told you, don't use your iPhone in extreme weather conditions. This information was modified on June 25 on the Apple iPhone website:

"Operate iPhone 3G and iPhone 3GS in a place where the temperature is between 0º and 35º C (32º to 95º F). Low- or high-temperature conditions might temporarily shorten battery life or cause the device to temporarily stop working properly."

When an iPhone is "too hot" the iPhone could stop charging, the display dims,  cellular signal weakens and a temperature warning screen appears with the message "iPhone needs to cool down before you can use it."

They warn "if this message appears, you should turn the device off, move it to a cooler environment, and allow it to cool before resuming use."

They also warn about extreme temperatures such as in the car and in direct sunlight.  Here's the strange part, according to the expert we interviewed, there is no way to turn off an iPhone if the screen is too hot to touch, because a touchscreen swipe by a naked finger is required or a specialized stylus.

We don't know if putting the iPhone in the fridge would work but we do know that the freezer is way to cold for an iPhone, but great for Hagen Daz.  Whatever you do, don't plunge the hot iPhone into an iced Latte.

If an iPhone or iPod has been damaged by liquid, the repair is not covered by the Apple one (1) year limited warranty or an AppleCare Protection plan (APP).  iPhone models and iPod models that were built after 2006 have built-in Liquid Submersion Indicators that will show (as described below) whether liquid has entered the device.
