nitpick: There is a native OpenVPN client for iOS in the AppStore. I don't know how they managed to, but it's plugging into the native iOS VPN functionality and it works perfectly well.

To my knowledge, there are 7 companies including OpenVPN who have been granted access to private VPN APIs. I personally use the OpenVPN iOS client for "always-on" phone VPN.

I see now. I didn't know there was a private API for App Store VPN clients. Cool, I will have to switch to using OpenVPN.
