I broke the glass on the front of my Iphone 4s, cost to fix it?

Yeah, I dropped my phone.
I've been looking it up, but some say the Apple Store will replace it for $200, another guy said they would replace it at no cost.
Is there anyone that works at the Apple Store or have experience with this that could confirm a price?

this is what it looks like

Melt it with a lighter. But be careful and apply fire gently

$80. Not sure if it is either for service or glass. Or maybe both

$199 at apple
