It looks like Apple’s iPhone 3G and 3GS phones can’t stand the heat [literally]. After being faced with a numerous stories coming from warmer countries, the company moved forward to release a temperature warning. According to the official Apple’s page, the acceptable operating temperature is ranging from zero to 35 degrees Celsius, e.g. 32-95 Fahrenheit:
"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."
Given the predominant summer temperatures, this would limit iPhone from use in most of California and south United States, most of Europe, complete Africa, Middle East, South Asia? all in all, in the end the device should be used freely in Alaska, Canada, Greenland, Iceland, Ireland, Norway, Sweden, Finland, Northern Russia and Australia during winter months [e.g. now].
It is normal that cellphone manufacturers issue temperature ranges of the devices in hand, but to state that the device should not operate at 35C air temperature is downright "crazy".
For comparison, the author of these lines uses a Blackberry 9000 Bold. Its operational temperature range is -15C to 50 degrees Celsius, e.g. 5-122 Fahrenheit. This means iPhone should not be used in countries that have winter or hot summer, as the country I currently reside dips even to -18C in winter and heats up to 40C in summer.
We are not certain what the heck happened with Apple and their design team. All we know is that Apple itself is located in the heart of Silicon Valley, and that place gets hotter than the allowed operating temperature for iPhone 3G and 3GS.
