Apple has recently released a support notice documenting difficulty operating the iPhone 3G S in hot environments, including normal outside use in 95 degree weather.  Older iPhone models and the iPod Touch are not specifically mentioned.

Undoubtedly, the iPhone has extremely high-end processing power for a mobile device, but it’s not alone.  Many smartphones are stuffed with bluetooth, Wi-Fi, high speed processors, HD video decoders, and have no known cooling issues of this sort.

However, let’s keep in mind that any electronic will overheat and malfunction if left in a car on a sunny day or exposed to other sources of great heat.  As the heat inside a computer or other electronic increases, the processing speed decreases as data “overflows” from improperly functioning silicon circuits.  This results in reduced performance, and in some situations, permanent damage.

This announcement from Apple should remind us all to watch where we leave valued electronics that can be damaged from heat.  However, don’t be afraid to pull your cellphone out on a hot day to make a call, as this sort of use rarely causes problems.  Is the iPhone 3G S an exception to this rule, a device only to be used in air-conditioned buildings?  We’re not certain.  The real question is, how will Apple warrant heat related problems in their devices?
