I dropped mine in the toilet as it was refilling after flushing the day I was moving out of my house. Literally it was the last thing before walking out. Everything was packed, including rice.
I knew enough not to try and turn it back on. I wedged it bottom first in to the airconditioner vent in my car and blasted it for a 3 hour ride. I let it sit for 2 days before I could move in to my new place.
I finally tried to start it and it wouldn't turn on. As a last resort, I plugged it in to my computer and it fired up with the Apple logo and started charging. The weird thing was that it was about 75% when I dropped it.
A couple of days later, the screen would get dim right in the middle of using it. See
here. A few more days passed and I was about to give up, it started working.
Good luck to you.
