Ubuntu Natty: Making a Gobi 2000 wireless modem work

In the pre-10.04 days it was possible to make a Gobi 200(0) modem work by installing gobi_loader and using it to load the firmware for the modem.

It might seem as if Nowhere.dk has been out of commission for a while. That is not the case – but a firewall configuration error (on my part) accidently blocked port 80; an error I did not see since I always use SSL. Sorry, Allan
