I dropped my iPhone in the toilet

I accidentally dropped my iPhone in the toilet. It still works, but the touch screen is unresponsive. I managed to turn it off somehow (unless it shut off itself). I'm at college so I have very limited resources to fix it. Right now I have it wrapped in a paper towel with cotton balls and snapped uncooked spaghetti standing up. What would you recommend I do? How long should I leave it before I try to turn it on? If I have to go to the apple store, what will they do for me? I don't have insurance on my phone. It's a 4s that I got last year. It was in absolute perfect condition (no scratches chips, cracks… Nothing!) Will they give me a discount or something?

Added (1). Please read the additional information. Have hardly any resources cause i'm away at college

Don't turn it on for two days. Put it in a bag of uncooked rice. You won't get a fully discounted phone, but they may over you the same model for less than full price. You can also take it to a phone repair center, and see if they can fix it. Whatever you do, do not turn it on and make sure you put it in uncooked rice!

Put it in dry rice for a couple of days at least. You can return your iphone to apple as long at it is less then a year old and is not jailbroken

I think you will be go to near mobile shop to repair the phone soon. If you will'nt gone your phone will be BYE BYE for ever. This is the only way.

Coming from experience I know the answer to answer your question!
I dropped my iPhone sometime this year, and it's kind of a long story so ill shorten it. I dropped it in the toilet, the screen was dull but everything worked fine, I put it in rice for a few hours, nothing happened, went to the apple store, they said they could repair it but it would cost more than the phone when you first bought it so it would just be better if you just bought a completely new phone! Anyways, I couldn't afford it at the moment so I put it in rice for a few days, it finally came on, everything was working fine so I went back to the apple store to check. It was perfectly fine I just needed to keep it in the rice for a little longer to soak the water and the Wi-Fi broke so I can't use Wi-Fi.

So!
Just put your phone in a bag of rice for a few nights or something, check on it once and awhile, make time and go to the apple store to get it checked. If not, buy a new one!
