USBfever has added two new products to its line of iPhone 4 accessories, the Solar Power Pack and Twine Leather Case. The Solar Power Pack for iPhone 4 is designed to guard the back and bottom of the iPhone, while charging the device via its built-in solar-powered battery. When fully charged the case can recharge the iPhone approximately one-and-a-half times, and still provides full access to all the phones features while itís in use. Apart from the solar panel users can also re-charge the case through the built-in USB Mini 5-pin connector.
