What happens to my iphone when it gets wet?

I have a black iphone4s but the problem is that my lil baby brother drop my iphone 4s in the toilet it stay there for 2 seconds but the good thing is that my iPhone 4s haded is cover on but when i pick it up from the toilet but mistake i turn it on but i turn it off i quickly dry it out with a towel and i turn it on it still works good but the problem is that i can't hear any sound from my iphone i could still take pictures and stuff is that i can't hear nothing? So i put my iPhone in a bag of rice so how long would it take my phone to work?

Added (1). by the way when i try to watch a video or play music i can't hear nothing I put the volume on it still doesn't work but i using it of a little while to listen to music it works but it only works with my earphones that's it! But when i take it out it still doesn't work? So i don't know what to do?

It may or may not work. I dropped mine in the snow for a couple of secs and it had the same thing as yours but the sound never came back. I had to get a new phone

Time will tell, but it doesn't sound good. Sounds like you may have to get it repaired my friend. Surprised it works at all lol

Phone is Damged
