How can I turn off VPN? I'm working on a friend's iPhone and every time I turn VPN off, it turns right back on. 

Have you ever seen this before?

Any suggestions for what I could do to keep it turned off?
Actually there is another step in here...

iOS > Settings > General > VPN > ~YourVPN_Profile (Click the 'i' icon) > Connect On Demand (turn toggle switch to 'off') = sorted!

NB. Use the VPN option under Settings > General... Not the 'VPN' switch under Settings!
