Remove all pieces such as battery, sim card, memory card. leave the phone open and you can use a hair dryer to try and dry it out quickly. let it dry for about 24 hrs then replace the battery ONLY the battery and try to power on the phone and check functionality.If everything works your good replace sim and all that. If its broken then your probably out of luck, unless you have a protection plan for the phone you'll have to buy a new one because that isn't going to be covered by any type of manufacturer warranty.
