put it in rice it worked when i accidently washed my ipod... leave it in the rice for a few days

Buy a new phone xD
Or, if you go to your phone carrier;(at&t,verizon, or whatever)
And ask for a new memory chip or card or something like that, or the battery.
The word for it has slipped my mind, but tell them what happened.
And I'm pretty sure that they'll mail you a new battery/memory card thingy for no charge.
But I could be wrong.
Because I got a free battery when I got it water damaged.
But we might have different carriers.

i dropped mine in the toilet, and take the battery out and blow dry it and blow dry the inside of the phone and google your phone and say what to do when dropped in water and it will have some stuff too.
water, tea, same thing. loll.
and if your lucky like me, it might just be the phone itself if its broken, so all u have to do is get a new phone but keep the media card and the battery thingie...

try putting it in rice. like a container of dry rice... leave it in there for a few days. It worked when my brother went in the pool with his phone in his pocket...
