What do i do to my phone?!? HELP!!?

haha i just did the exact same thing like a week ago. i kept mine in rice for about 5 days and it works perfectly now. A tip if it actually is in water, rinse it with distilled water otherwise the chlorine and other stuff will mess up your phones circuitboard and stuff. but i don't think that's nessasary in your case. oh yea and keep the bag closed, with some air inside
