Hello everybody. I recently installed FoxFI for a relatives phone so they could tether over wireless. I am rooted so I do not use FoxFI but I had a question about it's setup. I have searched and searched and for the life of me I cannot find one post that fully explains why I had to install a VPN certificate and add a PIN/lock to my relatives phone. Part of me wonders if this VPN they use isn't used for some nefarious purpose? Does anyone have a reliable source stating HOW foxfi uses this VPN to allow tether? I thought that the FoxFi site would explain it but they seem to have been swallowed up by PDAnet and their knowledgebase is less than perfect. Thanks in advance.
