The "latest" EVDO Rev-A USB modem for use on the Sprint MobileBroadBand EVDO network is the U-680. Actually, its not that new. Its the same Franklin CDU-680 that 3Gstore.com has been selling with Sprint EVDO service since Sept. 14, 2007 - nine months ago!
Sprint will be selling the U680 for $49.99 after a $50 mail-in rebate, but you can save $20 because 3Gstore is selling it for $29.99 after rebate!
