Samsung galaxy ace 5830i specifications ?

I Phone 4 with original box (crack on top right corner front)
Hi I am selling I phone 4 unlocked to any network with original box charger with adaptor and no headphones. I am selling because I have upgraded to a iPhone 5 and its just in my cupboard. The back is in perfect condition but on the front in the top right corner that is a crack not to major and can be repaired very cheaply but the rest of the screen is in perfect condition. Pick up is available or we can post it at your own cost.
