Liquid Sensor

[Bodah]

How many liquid sensors are there on the iPhone that turn red to show if the phone got wet?

I know about the one in the headphone jack, but I think I found another one.

I spilled a cup of water on my phone last night on the bottom side of the phone. Today when I was in the sun, I noticed a red spot in the dock connector. Sorry about the pic, I think the iPhone has a better camera than my digital camera.

Can anyone confirm this, or is the only visible sensor in headphone jack?

I have heard about a second sensor, and I think you're rght, that it is in the dock connector somewhere.

I can't make out much from that picture, but if that's your dock connector, I can say that nothing in my connector is red, much less as vividly red as whatever that dot is in the center there.

Apparently there was another post about this already.

I added a clearer picture there.
