Will Verizon replace my camera for iPhone 4?

So the black camera on my iPhone 4 has been really blurry when I try to take pictures, even when I try and focus it. So I think the lense is scratched. I read somewhere online that if you take it to the apple store they will replace it in a few minutes for only like $30, but I live in a small town and the closest town to us doesn't have an apple store. The closest apple store is like 3 hours away. But I'm going into town in a few weeks and it has a Verizon store, do you think that they would change it? Or is that just for buying phones? Thank you.

Added (1). * I meant BACK camera, not black

Hi, can you replace the camera by your own? It's very cheap to buy just 1pcs replacement. Welcome to visit www.tvc-mall.com to have a look.
