IPhone 4S 32GB white how much is it worth?

Wanting to sell my iPhone 4S white 32GB perfect condition only thing is that the lock button doesn't work, Evertying else perfect how much do you think I could sell it for tops thanks.

Umm, it is not in "perfect condition" if the "lock button" is broken, compare your phone to others like it on eBay then expect a little less.

I sold mine in perfect condition for 260.So if I were you, I'd try 240 or something like that.
