Oh no! I dropped my iphone 4 and now there's a crack on the screen

Today I dropped my iPhone 4 from Sprint and now there's a crack on the screen… There's only 1, and its like at the complete middle of my screen… I don't have a warranty. Is there any cheap way to get this repaired because its really anooying…

Buy an used one on ebay.

Yea get a screen on eBay and replace it yourself, I've done it before and it's pretty easy. They're like 10-15$
