Just about any electronics can comfortably survive a wash as long as it's not on at the time, and isn't turned on again until it's dry. That's kinda obvious though.
I've experienced dozens of MP3 players, cellphones, flash drives, cameras, and so forth take a dunking, get dried out, and continue to work without any issues.
The mistake most people tend to mistake when they drop their phone in the sink or whatever is they immediately turn it on to "make sure it's okay". Pull that sucker apart, remove the battery, and leave it in the hot water cupboard for a couple of days, then see if it's okay.
