Is there a way for me to fix my iPhone?

Well, yesterday my iPhone 4 fell out of my back pocket into the toilet. It was in there for maybe about 3 seconds. I took it straight out and put it under a cold hand dryer. It turned itself off so I ran home and put in on charge, the apple logo came on for 9 seconds and then the screen went black for 11, it did this every time, I left my phone on charge and went back to it about 5 hours later. I was so happy because it started working as normal! There was a slight watermark in the bottom left corner but i didn't see the problem because the screen worked fine. After about an hour of use, my phone came up with the temperature warning sign. It did this for about 10 minutes and afterwards worked as normal, but then did it again and now it hasn't left that screen since. I really really would appreiciate it if someone told me how to solve this because I've only had my phone for 2 weeks.

Hope you are insured, as you need a new phone. When you dunk any electronic device the first thing is to get the battery out; Oh sorry it's an iphone and you can't. Don't put power on it till it's absolutely bone dry, and say a few prayers to the appropriate Gods while you wait

Do the age-old drying trick. Remove all removeable parts, and bury everything in a bowl of uncooked rice. Leave in a warm place for 24 hours. Reassemble the phone and cross your fingers! Don't eat the rice though lol.
