iPhone Glass Shatters/iPhone Not Durable

I just dropped my iphone.. just one drop and it's ruined. I thought they made these things durable! I'm not sure a protective cover would have even helped in this case, because the glass front is what broke. I tried to get a cover early last week and the place I went was out of stock! Just my luck. The top front is shattered and there is a big crack down the front of the glass. It seems to be working ok in Brooklyn, where I live. But I was getting no service in New York City. I couldn't make any calls. I've heard that Apple won't cover this. I am willing to pay some money for this because it was half my fault, but Apple should bear some responsibility. I can't believe it broke so easily.. who doesn't drop their phone now and again???? Does anyone know how much this is going to cost me. Please don't tell me I have to buy a whole new iPhone at $600 price tag. I'm devastated.
