A long time ago I went to get my iphone looked at because the microphone was not recognizing the inline mic, Apple told me one of the water sensors was activated. Soon after the mic started working again. About a week ago I realized there was a crack on my iPhone about 1/2 of an inch in length (from the bottom by the 30-pin dock connector to about halfway to all the FCC symbols and warnings). Now even though it has water damage to you think Apple will replace the iPhone? And if they decide to do you think they would allow me to pay a little more to get an iphone 3g S, and if so what would you approximate that fee to be?
