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.

Yesterday Apple sent out a short and to-the-point message about using software hacks to unlock the iPhone, in which they basically warn not to do it. Apple has a new software update coming out for the iPhone in a couple weeks that among other things will contain the new iTunes Wi-Fi Music Store and could very possibly have something that will “take care” of hacked iPhones, intentional or not.

According to the statement issued by Apple, hacks that unlock the iPhone could cause the phone to be irreparably damaged after installing the update that Apple is planning on sending out, and these unlocking hacks are not covered under the iPhone warranty. Press release after the jump:
