I'm a computer repair guy ....and people bring us electronic-stuff that got wet....all the time....laptops, pda's, palms, pagers, pc's, cellphones, cameras, etc.
I hope you didn't try to turn it on.
Even if you did... you can try the basics I've learned on cleaning-up wet electronics:
rule#1 = even if it is not turning-on doesn't mean its dead.... it can come back to life if all the water is evaporated....meaning that the tinnie-tiny electronic circuits are no longer being short-circuited from the presence of water.
Now.... You'll need to remove the battery and then look for all the screws that hold the casing together. You'll need a tiny philipshead screwdriver (sometimes called an "eyeglass screwdriver") and a small flathead screwdriver to PRY on the edges of the casing to UNSNAP plastic pieces.
If you can get down to the circuitboard..... pat-dry and let it all air-dry for 3 days. Dont use a hairdryer or you'll end up melting some small pieces....you'll also be forcing water into small nooks-n-crannies. Just let air-dry...dont even blow a fan on it. just let it sit in the open air.
After 3 days... wipe down the circuitboard gently with a soft cloth and enough rubbing alcohol to barely get the circuitboard wet-looking.... a very thin film....not very much at all. Rubbing alcohol will find the micro-nooks-n-crannies where the water may still be hiding and will dry it out when the alcohol dries...it displaces the water.
After alcohol dries for a couple of hours... put all back together and it has a 50/50 shot of working again.
If it doesnt work after all that.... then have some fun by taking out your frustration by beating it to a pulp with a hammer. That's always fun. Us repair guys like to show who's boss by beating the living heck out of things... I know... I'm in counseling/therapy... hehehe
Good luck
