Ok I'm not that good with sciences and all, but here is what I'm thinking about. I shower, with my iPhone in the toilet too. I use a water heater. So, I was wondering, since after a while, the mirror in my toilet gets foggy. Which I think is due to the heat from the water I'm using. So.. I was wondering if this "steam" could somehow cause the water sensors to go off, if they condense on the cooler surface of the iPhone? Oh, and I don't touch it when I'm in the shower. (wet hands and all) -Summary- I hope not, especially since I'm careful not to get any water near it. Was just wondering whether the steam could get to the phone, tripping off the water sensors? Are they that sensitive?
