In order to install PdaNet builds manually without using Cydia, you need to be familiar with ssh and scp (download putty/pscp if you are using Windows). You also need to have OpenSSH (from Cydia) running on the phone.
- Download the PdaNet build (currently PdaNet417.deb) to your computer.
- Copy the deb file to your phone using any scp client.
- Ssh to your phone and run "dpkg -i PdaNet417.deb".
- If you do not see the PdaNet icon on your phone, reboot it
The PdaNet icon should show up in your application list.
