Looking at my old 3G, it appears that somehow the water sensor in my headphone port is no longer a bright white. The phone works fine and it has never been dropped in water, I just figure that it got hit with a rain drop or drop of sweat since in is exposed whenever I am on the phone. I would not like to have any more BS warranty issues from Apple, so I was wondering if there is any kind of dummy plug available for the headphone port? Anyone know of anything? A few searches later, I have only found items for the original iPhone.
