My iPhone 3gs got a little bit wet from the sweat of my glass near the charger jack & speaker/mic yesterday. I examined the sensors and they're still white. However, today my audio stopped working on the phone - I couldn't hear anything from the speaker OR the earpiece. I'm not sure if this is related to the water because the earpiece didn't work either... I turned it off then back on, it works now. I was wondering if I may encounter future problems? Or is this common anyway? I'd rather not have to take it to the store & deal with not having it for a while. Anyone had any experience? Thanks.
