When you dropped it in water, what exactly happened and what did you do? Was the phone on? Did it still work when you took it out?
What you should do is immediately turn it off, and then leave it in a bag of rice for several days. If you attempt to turn it on, you pretty much destroyed the phone with no hopes of bringing it back.
