Iphone 4s 16gb. Unlocked. Very good condition $160 OBO

I am selling my iphone 4s. It is in perfect condition except for the "lower volume" button that doesn't work. It is also unlocked and can be used with any carrier, nationally or internationally.

I have the original box and charger, and I always used it with a case, so any scratches are minimal.

It is updated to ios 8.

Let me know if you have questions, cheers!
