Yesterday, US Patent & Trademark Office published a patent application from Apple that reveals a rather inventive idea of fighting grime on your iOS Devices. We were the first to reveal Apple's initial patent on this subject in August that focused on using a vaporizing method involving a physical vapor deposition chamber. In Apple's latest method, they reveal an alternate method of fighting grime that uses mechanical wave mechanisms that could use audio or physical vibrations. The interesting fact is that Apple has expedited this patent application which was only filed seven months ago. Apple is apparently out to fight grime on all iOS devices in the future, and before you know it, they'll be called the Grime Busters! That's right: Who ya gonna call? Grime Busters!
