Sprint is trying to get on the iPad bandwagon without actually offering any iPad services. They are marketing a special 4G iPad case that has a special pocket for their 3G/4G mobile hotspot.

"The 4G Case has a pocket to house an Overdrive™ 3G/4G Mobile Hotspot, so you can simultaneously connect your iPad™ and four more Wi-Fi enabled devices at 4G speeds anywhere within 4G coverage areas. Meaning now you can use your iPad™ for everything it was built for, and then some."
