Wireless provider FreedomPop, the company providing access to free monthly data plans through a number of hotspot devices and iOS device accessories, today announced it is expanding its 3G coverage through Sprint’s network to provide nationwide coverage to its customers.

In addition to the network expansion, it is also now accepting preorders for its latest hotspot device dubbed “Overdrive Pro” (pictured above):

FreedomPop offers users free data (with the option to purchase more) ranging from 500MB to 2GB per month through devices such as its $99 WiMAX sleeve for iPod touch or the recently announced $89 Burst 4G home wireless router. It also has an iPhone 4/4S case that is awaiting Federal Communication Commission approval and told us in February it plans to roll out LTE service and a new LTE iPad clip later this year.
