I dropped my iPhone 4S in water 2 days ago?

I dropped my phone in the toliet 2 days ago and it was in there for about 4 seconds. I put it in rice and let it sit there for 2 days and i went to go turn it on yesterday and nothing. Can anyone help me? I really don't want to buy a new iPhone and I want the cheepiest solution.

Drop it off to a phone shop. DO NOT try to open it yourself unless you know what you're doing.
Ask them to just TELL you what's wrong, and if the price of reparing seems alright then go ahead. If its too expensive then try to buy a second hand iphone from ebay. There about £200 or so
