But will Apple void the warranty just for applying this?

I’m fascinated by how it can apparently seal even the electrical contact surfaces in the ports for USB cord, the SIMcard and the headphone jack so as to prevent accidental water across those surfaces from causing shortcircuits there, and yet, somehow, that waterproof seal on those contact surfaces won’t also interfere with normal electrical signal transmissions/currents between those surfaces and the USB cable, SIMcard or headphone jack.

Pure water is a poor conductor. Now the crap in the water is a different story. I’d wager that their test tank pictured there is pure water. Tap water will conduct some because of the minerals and other chemicals in it.

And not wear off by plugging cables in and removing them.

Old timers hear may recall the story about my iPhone 3G swirling down the toilet. It fell out of my shirt pocket while I was cleaning the toilet, I grabbed it though I doubt it that it could negotiate the trap. Fortunately the water was clean, I was giving it a second flush, but yeah even tap water has minerals. As an old “Salt” I can tell you about the importance of distilled water in ship’s boilers.
