USBModem is downloadable software. It is made by Mobile Stream. Free 14 day/30 connection trial. It is $19.99 to register. And it is supposed to work with bluetooth and through the USB cable, yet I was only able to get the cable part working. It was late and I was frustrated so I didn't try but once, and maybe later I will get it to work. The truth is USB connection gives you true EVDO speeds while Bluetooth does not, so in the even that I have no Wifi spot to connect to and need a modem I usually use the cable anyways.....

I just needed something that worked, and USBModem does...

Hope I answered some of your questions....
