How much should I sell brand new iPhone 4 with small crack (black) for?

My dad bought it for me but my little sister dropped it, I didn't know that my nan bought me iPhone 5? So how much would it sell for?

Without a crack I have seen them selling for $225. I just priced them 5 minute ago on craigslist. With the crack it would be hard to get over $150 for it. Sorry to hear that happened.

£250 to £300 seems like a good place to start. BUT this depends on the size of the crack and if the phone functions like new. Which I guess it does. As usual you can sell it on Ebay or if you can't wait take it down to your local CEX or Cash converters and see how much they can offer.
Best of LUCK.

Do some research on ebay. My guess is £200 as it is 2 generations old and obviously not new. But this can depend if it is unlocked and if the screen has the crack in it etc.
