How much should I sell my Iphone 4s for with Flappy Bird?

I've heard that the price for an Iphone with Flappy Bird has been expensive. I have a white, 16GB Iphone 4s with this app. However, my phone has a couple of flaws:

1) Front screen has a crack going across the top of the screen.
2) Sound doesn't play from the speakers.
3) One of the volume buttons is jammed and can no longer be pressed in.

How much do you think I should sell it for? I know these imperfections will lower the cost, but I also know that apple stopped carrying a 16GB 4s, so that might help a little bit. I'm just trying to get a new phone.

However much the iPhone itself is worth. The maker of Flapper Bird, Dong Nguyen, announced that he is putting Flappy Bird back in the App store, solely because he thinks it's unethical and wrong that people were selling their phones with the game on it for outrageous prices. From what I understand, the hype about these iPhones being sold for insane prices with Flappy Bird came from some bidding on Ebay that showed brand new iPhones with Flappy Bird going for as high as $100,000. However, just because people bid on an item for a high price, doesn't mean they actually intend on paying it! They're just trolling, no one in their right mind would actually pay $100,000 for a phone with a stupid app, they're just trying to stir up some trouble.

People are asking that much but no one's buying them.

There was one iPhone that sold for a couple hundred dollars with the app Flappy Bird, and it went on the news. It happened once and was stupid.
