Go to the Sprint PCS website and download the lastest dialer software. You can use the cradle as the link from your phone to your computer so additional hardware is not needed. Once you download the software, then follow the intructions to install the Dialer and Bluekite software. Remember, normal speeds for a dial-up service is at 56k and using your I300 as an ISP is at speeds at 14.4k so it will be very slow. But, if you upgrade to the new I330 and use the new Vision network, speeds can reach up to 300k...almost as quick as DSL. Downside, using your cell as a ISP will take away from your minutes. Good luck!
