Apple iPhone 8GB AT&T 3.1 MA712LL (Works great)

My sister used this phone for a bit and then changed carriers.  It's an awesome phone.  The screen is crisp and there are no cracks.  The back of the phone shows some dings and scratches but they don't affect functionality.  I don't have any accessories.  This auction is for the iPhone only.
