Have you ever got a warning message on your iPhone which says "iPhone needs to cool down before you can use it".
According to Apple's knowledge base its for real:
The iPhone blog reader, Jeff got this error while he was sitting next
to a pool in Scottsdale Arizona where the temperature was 104 degrees.
When I saw the screenshot for the first time, I thought it was fake but Apple's Knowledge base confirms that its for real.
As per Apple's Knowledge base:
Note: When this message appears, iPhone 3G may still be able to make emergency calls.
Some conditions and activities that may activate the Temperature warning message:
Leaving iPhone 3G in a car on a hot day.
Leaving it in direct sunlight for extended amounts of time.
Using certain applications in hot conditions or direct sunlight for long periods of time, such as GPS tracking in a car on a sunny day or listening to music while in direct sunlight.
Jeff's figured out a neat way to fix the problem:
It's good to know that Apple has even thought of how to prevent the
iPhone from overheating to protect its components from damage.
Have you seen this warning message on your iPhone?
Thanks Egypt for the tip!
