- Go to a command prompt
- Run "gconf-editor"
- Go to System->Networking->Wireless->Networks (left pane)
- Click on each Wireless Network's "folder" (left pane)
- Right click on each key in the folder and choose "unset key" (right pane)
- Repeat for each network you don't want to auto-join
- Quit gconf-editor
gconf will soon update your config to remove the "folders" for the unset networks
