Apple issued a temperature warning for their 3G and 3GS iPhones this week. Perhaps the summer heat was killing a few of the fancy phones in North America.

"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.

Store iPhone 3G and iPhone 3GS in a place where the temperature is between -20º and 45º C (-4º to 113º F). Don’t leave the device in your car, because temperatures in parked cars can exceed this range," said Apple's website.

If you are bringing your iPhone to the beach, or over to similiar summery places, like Disneyland, it should not be that hard for your iPhone to exceed 32ºC -- especially in the hotter climates. So watch out! If you exceed this operating themperature, the horrible following problems may befall your so called 'smartphone':

• The device stops charging
• Display dims
• Weak cellular signal
• Temperature warning screen appears with the message "iPhone needs to cool down before you can use it" (see image below)

This somewhat limited operating temperature range might really be a problem this summer for owners in hot places, like South Africa or Bali.
