SPRINT HAS FINALLY ANNOUNCED that they will begin selling their first 3G/4G mobile hotspot next week on January 10th.  The successor to their current mobile hotspot offering, will allow users to connect laptops or any Wi-Fi enabled devices to its 4G network.

The release of Sprint's Overdrive arrives just as Sprint is beginning their expansion of their WiMax network, which is available in 27 U.S. markets.   Overdrive will help overcome issues with the lack of 4G devices by allowing users to access the Internet with any device that uses Wi-Fi.  Sprint plans to expand their coverage by a factor of four by the end of 2010.

The ability for users to switch between the WiMax and 3G networks means users can still access the Internet in areas that aren't covered by the WiMax network.
