A Water Sensor in iPhone and iPod Touch!?
I never knew the iPhone and iPod touch has such a sensor!
Let’s say you drop accidentally your iPhone in water (not sea water as salt will be easily spotted), you can always try to send it back to Apple Support for having it repair under warranty. To avoid such behavior, Apple has included a water sensor in the iPhone and in the iPod Touch HardMac Forum

Cell phones have had this for a long time. I’ve got an old Nokia that has this behind the battery. It has apparently gotten enough moisture on it to activate, since it’s turned bright Pink. Pretty smart to put it at the end of the headphone jack like that, one of the few internal parts of the device(s) that can be accessed without cracking the unit open.
