Sprint first had the 4G iPhone commercial, now they have introduction of the Sprint 4G Case for iPad. Available for free at Best Buy with the purchase of a Overdrive 3G/4G Mobile Hotspot. The case will not only protect your iPad, but it will also protect Overdrive Mobile Hotspot.
This move to for Sprint to use the iPad as there main target is not the best idea. The ipad right now is not the best selling gadget, nor do the owners want to use the smallest call company. At the same time many people who bought the Wifi version want to use a fast network like the Sprint 4G.
