I have just spilt a whole cup of tea on the kitchen worktop and it went all over my Iphone. everything is working apart from the sound. I can here music and phone calls if I have my headphone in or put it on load speaker, but not normally. Will this correct it's self or have I blowen up the main sound speaker. If I press the button on the side which adjusts the sound it keeps saying that I have headphone in which I don't.
