Devices have survived. Theoretically, they run on flash memory, and you can literally wash flash drives and they still work. I've done it. The water doesn't as much damage the device itself as it causes damage by way of short circuits as drops of water causes the power in the device to arc where it's not supposed to be, shorting things out. Hence why you don't turn it on, dont' charge it, keep it as inactive as possible.
Let it sit in the dry rice for days as suggested. Rice is a natural dessicant....as in dries stuff out and absorbes moisture - why you see restaurants using it in their salt shakers to keep the humidity from caking the salt.
THere have been peopel on this forum that have reported the rice working. At this point you have nothing to lose really. A chance is better than no chance.
