A number of reports today have pointed to an Apple support document providing advice on how to keep iPhones from overheating as an acknowledgement of the problem on the part of Apple. As Macworld points out, however, the document was originally posted many months ago, and was recently updated only to add references to the iPhone 3GS to the existing ones for the iPhone 3G. According to the Apple document, an overheating iPhone will display a warning screen and become inoperable with the exception of allowing emergency phone calls to be made. Apple also describes several situations that can lead to activation of the temperature warning screen.
- Leaving the device 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.
