Sprint has finally started a hushed down rollout of their EV-DO high speed wireless service. They have recently turned the service on in the Port Columbus International Airport, Charlotte International Airport, Columbus, Ohio, and Kansas City. The next cities scheduled to receive Sprint’s EV-DO treatment are Las Vegas, New Orleans, Cleveland, Raleigh-Durham, Des Moines, and St. Louis. While this is certainly a move in the right direction for Sprint, one of the last ones to enter into the high speed mobile data services, they have yet to release any EV-DO capable phones onto their network, therefore you will need to use the Sierra Wireless Aircard 580 card to use the service.
