Sprint may not stock the iPhone or the iPad, but that hasn’t stopped them from reaping the benefits (or even making a case) of the iPad’s success. In an interview with GigaOm, Dan Hesse,CEO of Sprint pointed out that the fastest selling iPad’s were the WiFi variants, which bodes well for Sprint. Sprint’s Overdrive 3G/4G mobile wireless hotspot, has been selling well, allowing iPad owners to blitz the net at 4G speeds. “The company has seen an uptick in demand for its Overdrive (3G/4G) MiFi wireless hotspot device, as people use it to connect their iPads to the Internet when on the go.” Although Dan stopped short of giving us some actual numbers, we’ll give him theĀ benefit of the doubt. Sprint has been rolling out their 4G network gradually across the major cities in the U.S., and from the looks of it, their Overdrive sales aren’t going to pipe down any time soon.
