try taking the battery out and blow dry everything and let it sit for about and hour or two right away! if that doesnt work stick it in a bowl of rice white rice, i washed my phone in the washer and i did both and now it works perfectley fine!
take it all apart - take the battery out too. Put it all in a bag of rice for a day or two. It worked with my Blackberry when I dropped it in the toilet
Take it apart and take out the battery. You need to dry it out. Use a hair dryer on the lowest setting to help it along. Don't get it too hot. This worked for a friend of mine.
