For the past few days, users of the new iPhone 3GS have been complaining through various blogs and forums about heat related issues with the device. It's not clear how severe or widespread the problem really is as Apple has not issued an official comment on the reports. While not admitting to any flaws, however, they have posted advice on keeping the iPhone 3G and 3GS within acceptable operating temperatures. This includes not leaving the phone in the car or exposing it to direct sunlight for extended periods.
Of course, this applies to just about any electronic device, but they also suggest avoid using certain applications for too long. Furthermore, according to reports around the web, the iPhone's internal and ambient temperatures can spike when performing multiple functions simultaneously. Some examples of this include using the iPhone while it's charging, using Wi-Fi during phone calls, and accessing data services during phone calls. In the case of the white model, the heat has been enough to cause discoloration.
If you happen to own Apple's latest and greatest smartphone, let us know your thoughts in the comments. Is the 3GS really that prone to overheating or is this issue getting blown out of proportion?
