FreedomPop is now taking pre-orders for its embedded WiMax and LTE iPhone 4/4S case, which first appeared in March. The company is the latest brainchild of Skype founder Niklas Zennstrom and aims to offer users ëfree wireless broadbandí using a freemium service model. Users who put down $99 for a case will get up to 500MB of free data per month in an iPhone accessory that offers users the ability to access 4G speeds, FaceTime video calls, as well as the ability to act as an external battery charger.
