[Video Link] The FreedomSleeve is an iPhone sleeve that connects a 3G iPhone to a "free" 4G network. It can be used as a wifi hotspot, and has a built-in battery to extend the iPhone's internal battery an additional 6 hours. It cost $99 and you get "up to 1GB of free data every month." According to GigaOM, each additional megabyte will cost a penny. Service is expected to start this summer. I hope the service is international. Freedom Pop iPhone Sleeve
