iBattz has unveiled its new Mojo Armor and Mojo Vogue removable battery cases for the iPhone 4 and iPhone 4S. The Mojo Armor is a rugged, impact-resistant battery case offering integrated port covers for the headphone jack, micro USB charging port, and ring/silent switch, push-through coverage for all other ports, two included, swappable 1700 mAh battery modules, and a built-in power on/off button. The Mojo Vogue also includes two swappable 1700 mAh battery modules, but features a slimmer design that offers open access to all ports, controls, and cameras—save for the Dock Connector—and comes in a wide range of colors. Pricing and availability for both cases has yet to be announced.
