yeah the rice trick works. A friend of mine did it on her iPhone when I told her to give it a go.

fully submerge it in the bowl of rice, leave it over night. Disgard rice afterwards

Altho, it would only be a temporary fix, as phones when wet will eventually begin to rust over time, so I would say you might be looking for a new phone in a year or 2 anyway, but lets face it, who keeps a phone that long anyway!
