What kind of nano is it and when did you buy it? I washed the ipod nano 2nd gen i bought about a year ago, opened it, messed it all up, put it back together, gave it to the apple support people, and got a brand new one back. So if you would still have had warranty, just go and see them and they'll probably give you back a new one without even looking at it (as long as you put it back together a bit)
