Take apart your phone (battery mem card etc. and put all the pieces covered in a closed bowl of rice. (not cooked) for a few days. Works great. I always get my phone wet and it still works.
Rice works. I've done this every time i spilled anything on my phone and it absorbs the water and you should be able to use it again depending on how long it's been since it got wet.
put it in a bag of rice for a couple of days. it will absorb the water. make sure the rice is not cooked :)
