I have for sale a Mophie Juice Pack Air for the iPhone 4. For those who don't know what it is; here is some info from their site. This is in perfect condition with no scratches or dents, and is in perfect working condition. I don't know where the charge cable went but all you need is another USB-micro cable (which you can get for $5). This retails for $80 + tax, i am looking to get $50 + shipping. price is firm.
