Sprint Overdrive dual-mode WiMAX / EV-DO mobile hotspot leaks into the wild (update: $50 U301 on contract?)

Move over, MiFi -- this Sprint Overdrive dual-mode WiMAX / EV-DO mobile hotspot that just hit our inbox has taken over as our new object of broadband desire. Our tipster says internal training on the Sierra-built device has already begun, and that the unit itself features a microSD slot, support for location services, and has a 100-foot Wi-Fi range -- but sadly we don't have pricing or availability deets to share yet. We're hoping we find out more at CES -- and we'd bet that new dual-mode U301 WiMAX modem that leaked a couple weeks ago makes an appearance as well. Fingers crossed.

Update: The same tipster that sent us the information to start with is back with a few tidbits on the U301. According to the anonymous individual, that USB modem will be launching in February for $49.99 on contract. Also on the horizon? A WiMAX home desktop modem with a special price plan of its own.
