Apple has submitted a patent application for technologies which would detect device-abuse by consumers. The intent presumably being to aid in determining the validity of warranty claims. 'Consumer abuse events' would be recorded by liquid and thermal sensors detecting extreme environmental exposures, a shock sensor detecting drops or other impacts, and a continuity sensor to detect jailbreaking or other tampering. The article also notes that liquid submersion detectors are already deployed in MacBook Pros, iPhones and iPods. It does seem reasonable that a corporation would wish to protect itself from fraudulent warranty claims; however the idea of sensors inside your portable devices detecting what you do with them might raise eyebrows even beyond the tinfoil-hat community.
