Sprint announced the industry's first dual mode 3G and 4G device today, the Sprint 4G U300 (by Franklin Wireless). This USB dongle will allow you to access all of Sprint's mobile broadband networks, including EVDO Rev-A and WiMAX! Currently, 4G is ONLY available in Baltimore, but they will be expanding throughout 2009.

The device will cost $199.99 with a 2 year contract and will be available after 12/21/08; the monthly charge will be $79.99 for EVDO and 4G access. It is unclear what the usage limits will be, but I'd imagine it would be 5GB like most mobile broadband. Unfortunately, it is NOT Mac compatible, which is strange, since all other Franklin devices have been Mac compatible out of the box - this is probably because they don't (yet) have Mac support for their 4G network at all.
