If you need to carry around a USB drive and own an iPhone 4/4S, the Premium EGO Snap Hybrid Series Case Cover is the perfect spacesaver for your pocket. The case not only protects your phone from drops and scratches with an attractive resin case in a number of colors, it also comes with an integrated USB flash drive that fits right into the back of the case. Just slip it or out of the case as needed- no need to fish around your pockets looking for the tiny drive, it will be right on your phone. Smart idea.
