Dropped my iphone4s in water and now i can't hear out of it at all.what do i do?

I Dropped my iphone 4S in the sink while doing dishes about a half hour ago. Now i can't hear music out of the speaker or the headphones and if someone calls i can't hear them and they can't hear me. I can still text and everything like that but there's no sound. I have it sitting in rice right now but its not completely off its in stand by mode. What do i do please help me

Need to dry it out, put it in the airing cupboard overnight and if your very lucky sound might come back.
