Freemium wireless Internet startup FreedomPop made good on its word by kicking off its public beta earlier this month and hocking USB modems and mobile hotspots, but that launch left many of its would-be users asking one question: Where are the iPhone and iPod touch cases the company unveiled all those months ago?Well, that wait is over… for some people, anyway. FreedomPop has just announced that its WiMAX-capable iPod touch cases are now shipping, and will set potential users back a cool $99 should they decide to take the plunge.
