My Iphone 4s plus button is broken will the apple store let me get Iphone 5?

I'm on a Verizon wireless contract and I have insurace on my iphone 4s that I have for 5 months. My plus volume button on my iphone is not working. My local verizon store told me to go to an apple store to see if they will fix it. My question is do you people know if They will let me imididly upgrade to the iphone 5 without the full 199.99 price?

No I don't think so. Maybe they will fix it, I don't know how they do in your country. If they don't, you can search a store which specialized to fix iphones. There are many of them and not so expensive.
But I'm about 100% sure you can't get an iphone5 for your old.

But if they give you one, write me immidiatly! I will smash all iphone4 I can find against a wall and get rich.
