In that case, my recommendation is to try and get it replaced, then buy the most protective, shockproof case you can find (that, or stop dropping it 🙂
If they replace it, lucky you. If not, you got lucky three times already.
If they don't replace it, and you let it sit and it doesn't work after it completely dries out, then you have nothing to lose from trying to take it apart and fix it.
