Amidst rumors of overheating iPhones since shortly after the iPhone 3GS was launched, Apple has finally released the first acknowledgment that there might really be an issue with the iPhone regarding excessive temperatures. Various sites on the internet have posted reports of problems with the iPhone due to excessive heat such as shortened battery life, shut downs and even discoloration of the device itself. Now Apple has officially issued a warning about operating and storing the iPhone 3G and iPhone 3GS in places with too much heat.

Apple suggests to only operate the iPhone 3G and 3GS in temperatures between 32º to 95º F (0º and 35º C) and to only store the device between temps of -4º to 113º F (-20º and 45º C). Using or storing the iPhone in temperatures beyond this range can cause the device to stop charging (which could explain a shortened battery life), a dimmer display or a weak signal.

It wasn’t long after the Blackberry Bold went on sale in Japan, that DoCoMo had to pull it off the shelves after reports of early adopters having possible overheating problems. Of the 4000 units sold, DoCoMo was notified of about 30 such complaints.

The numbers don’t seem that big, but DoCoMo is being cautious and halting sales, pending an investigation from Blackberry . You see, unlike this country, service is big in Japan. So far Blackberry has been able to deduce that the problem is not with the battery and says that this issue is limited to only Japanese Bold phones.

A 12 year old Michigan Middle School student had his PSP in his pocket during band practice, when the battery overheated, burning a hole in his pants and sending him to the hospital with leg burns. It seems that in this particular school, students are allowed to have the systems with them as long as they don’t play them during school hours. A policy which I am sure will change after such a close brush with what could have been a case of char broiled genitals.

Sony has been quiet so far regarding the incident. No word on whether the kid was using a third party battery inside the system or not. Much to the kid’s dismay, after being treated he was back in school later in the afternoon.
