USB modem

[modifiedbear]

I've searched around for an answer so try not to bite my head off if I've missed something.

I'm sure a lot of you are familiar with this program http://www.mobile-stream.com/usbmodem.html

I'm trying to find something out there that does the same thing, but doesn't cost anything. I have a computer I dual boot Windows and OS X on so using just ICS isn't ideal.
