NOTE:  We strongly recommend the OpenVPN for iOS client is used on iOS devices, along with the Open VPN configuration files.  Although the method detailed below can be used to connect from your device, it uses preshared keys which is a security risk for some people.

The Open VPN Application for iOS can be found here.

OpenVPN configuration files can be found in the control panel.

Alternatively, here are setup instructions using a (public) preshared key.
