Excellent condition, always used case and screen protector.
Running iOS 9.
Includes everything it originally came with: box, lightning cable & power adapter, earphones, even the Apple stickers.
Unlocked, so you can use it on the network of your choice.

You can have the case I used for free. The case is a little beat up, but that's why the phone isn't.

$225. Pick up on Stanford campus.
