Depending on your track record with Apple products, they may replace it for you for no charge. I've had desktops, laptops, and I was on my second iPhone last year when I dropped it and killed it. I brought it into a Apple store, they originally told me it would be about 200$ to fix the screen, I didn't complain since it was obviously my fault. After going back for the new one the service guy told me it was no charge.
