Iphone cuts off? How to Fix?

A couple days ago i dropped my Iphone in some water i did the whole rice thing and plugged it up it came on. Then it asked me to connect to itunes for IOS6 but everytime i unplug it in it cuts off and when i try to put it into my computer the apple logo come on and then the phone shuts off. Anything i can do that will get my phone working properly again?

Go to the apple store or your carrier store and get a replacement. Explain what your situation is and they should give you one. I had a similar situation, they gave me a free one.
