Don’t worry, everybody, your iPhone baking itself to a crisp is no cause for panic, now that Apple has found the culprit: the weather and your heartless negligence. Apparently you’ve been leaving your brand new iPhone 3GS in a hot car, and the warm sensation you feel any time you hold the phone has nothing to do with beefed up processors or inadequate cooling. Phew , glad that’s all sorted and now nobody will have any problems with self-destructive iPhones they paid hundreds of dollars for. Besides, it serves you right .

Exclusive: Bill Nye the Science Guy was gracious enough to elbow Matt out of the way and write a Giz Explains column, in which he tackles the science of “oleophobia,” and its relation to the new iPhone screen. The new 3GS iPhone has a coating that helps you leave no, well hardly any, prints–-fingerprints. The glass screen is coated with a polymer, a plastic that human skin oil doesn’t adhere to very well. People in the chemical bonding business like to call the finished surface “oleophobic.” Such a lovely Greek cognate may sound like it means “afraid of oil.” And, it does, but it also connotes (or carries with) “aversion” or “not-like-to-be-around-tivity,” if I may. Instead of sticking to the bonded-plastic surface of your new phone, the oil from you fingers or cheekbone or tip of your nose stays more or less together as its own smooshed droplet. The Applers were able to do this by bonding this oleophobic polymer to glass.
