Sprint has announced its first 3G/4G USB Modem U300, which is compatible with Sprint 3G network and also the 4G WiMAX Now Network. Sprint launched 4G in Baltimore in September and plans to launch in other markets across the country throughout 2009. The Sprint 3G/4G USB modem will access mobile multimedia applications at average downlink speeds of 2-4 Mbps within Baltimore Sprint 4G service areas. Where Sprint 4G service has yet to launch, the dual-mode device will operate on the Nationwide Sprint Mobile Broadband 3G Network at average downlink speeds of 600 Kbps – 1.4 Mbps.

The Sprint 3G/4G USB Modem U300, manufactured by Franklin Wireless, is priced at $149.99 with a two-year subscriber agreement, after a $50 mail-in-rebate. Beginning Dec. 21, customers can purchase the USB data card via the Sprint direct business sales force, at most Baltimore-area Sprint stores and at select Baltimore-area retailers. Starting in January, the device will also be available in Baltimore-area Best Buy stores.
