Key Product Differentiator: We are the only iPhone battery replacement kit on the market today that includes a suction cup for removal of the touch screen glass. Our competitors leave it up to the customer to figure out glass removal. Without the suction cup, users are forced to use screw drivers and other tools to wedge the glass out of the case. Tight case tolerances on the iPhone 3G and 3GS make this is a difficult task. This can lead to a scratched or cracked touch screen. Use our products and services and we'll ensure success with the least amount of effort.
