I'll have to disappoint you. Leave a wet iphone with the power - this is exactly what NOT to do. Perhaps you do not carefully read our answer to the question "iPhone water damage. What to do?" If after all the procedures to restore the wet iphone is not responsible for your actions, without proper training you will hardly be able to fix it.
I recommend you to contact the Apple customer service. All is not lost.
