There’s been quite a little buzz building around FreedomPop thanks to its ambitious plans to provide freemium wireless internet to everyone in the United States, not to mention its peculiar 4G-friendly iPhone cases. As it turns out, that’s not all that the Niklas Zennstrom-backed company has been working on behind closed doors. FreedomPop has just announced that it plans to release another 4G-capable case — this time meant for use with the iPod Touch — and has already begun taking pre-orders for the $99 gadget. “We’ve had thousands of inquiries,” FreedomPop marketing VP Tony Miller told me. “[The iPod case] was further down on the roadmap, but we had to push it up.”
