To be honest I had a EVDO Rev A. USB modem from sprint, and it was awesome. Fast and reliable, and I used it with my MBA. I got an iPhone and decided to drop the Sprint modem, and download PDAnet. It does work, but is is not near as reliable as the Sprint modem. That is what I mean about cheap. THe Sprint modem was $60.00 a month, wheras PDAnet is $30.00 total.
