The iPhone 4 case kit is called Third Rail System that consists of two parts, including an ultra slim iPhone 4 to protect your iPhone 4 from scratches and bumps, and a portable rechargeable battery with 1250mAh capacity that measures 3.29 x 1.83 x 0.27 inches and weights 1.4 oz. As we can see from the images, the back up battery hasn’t been integrated into the case. This means the battery doesn’t always add some bulks to the iPhone 4 case.
