I am trying to sell my Iphone so I can get some new ski gear, I just got back from the Navy and need new gear. The Iphone is the 3GS updated so its running the iOS 4.1. 16 gigs of memory. It did have a screen protector on but it started to bubble so i took it off. Screen has minor scratches. the back of the phone has marks from the case I had on it. The worst part about the phone is it fell out of my pocket and get a dent by the vibrate switch. The silent function DOES NOT work. You can still turn the volume up and down, but not turn silent mode on. Phone is guaranteed to work. The phone will come with wall charger, usb cable, one regular case, and one battery case that will almost double the battery life. Any questions/offers just shoot me a pm. Price is OBO.
