NESPOT in South Korea

Does anybody out there have any advice on how I might get my ibook to connect to the HUGE wireless network in South Korea called NESPOT? I paid for the service (15,000 won/month) and still have no capability of browsing the internet using my ibook. The closest I get is that my airport extreme seems to detect the connection with NESPOT. Because I wasn't able to download the NESPOT software (it's windows only), I am not able to use the connection that my ibook is detecting. I wouldn't have even bothered except i saw on other forums that people say "don't give up! you CAN connect to NESPOT using your ibook!" so i did it, and now I feel that 1) i've wasted 15,000 won, and 2) my ibook is really going to be of little use to me this year while i'm in korea.
