Apple has acknowledged that its new iPhone 3GS may be having some issues with regards to temperature its new smartphone can reach under normal circumstances.

The company has been forced to issue a set of guidelines that will help users keep their handsets within a comfortable temperature range, thereby avoiding overheating problems.

The iPhone 3/3GS they say, should be operated "in a place where the temperature is between 0º and 35º C". Failure to do so could shorten the battery life or cause the phone to temporarily stop working.

The manufacturer suggests that the phone be stored in places where "the temperature is between -20º and 45º C (-4º to 113º F)". Temperature in cars, it says, will often exceed the upper limit.

It also advises users not to use resource-hungry applications like streaming media or GPS over a long period as they put significant strain on the device's hardware.

Failure to follow these could cause the display to dim, weaker cellular signal and finally a temperature warning may appear on the device's screen saying that the "iPhone needs to cool down before you can use it".

Apple's move comes after reports that white iPhones tend to turn pinkish brown quickly due to overheating. Furthermore, it also looks like the new iPhone OS 3.0 update might cause older iPhone 2G and 3G to overheat

So it is a case of "please don't use it for applications we designed it for or it'll cook your ear !"

Utterly marvellous.

probably a good idea to wait a while and see if they last a couple of months

Normal body temperature, 37 degrees C. So guess you can't keep it in your pants anymore.

Even the 1st gen iPhones get baking hot when pushed.....I'll hold off my purchase for a while i think.

A friend of mine from the US told me that many customers were returning their phones because the battery life is pathetic. The heat issue wasn't mentioned.

Small wonder ya dont get laid

Guess it's because the processor is twice as fast... anyway would not overrate this report. They sold 1M of these on the first weekend and there haven't been recalls or massive return rates so I think it's OK.

Products Affected

iPhone 3G, iPhone 3GS

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.

If the interior temperature of the device exceeds normal operating temperatures, you may experience the following as it attempts to regulate its temperature:

• 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"
