I can actually turn the OpenVPN connection on and off through the system switch.
Strangely that turned to work when I try to fix my VPN-on-Demand setup which broke after updating to 1.02.
Before my VPN-on-Demand setup worked like a charm. I used this guide:

but it refuses to work after updating to OpenVPN 1.02 on iOS.
I just found out that after importing the .mobileconfig setting for VoD when I go to settings -> VPN and at this setting uncheck the "connect on demand" button, I can actually turn it on through the System settings.
That's a nice find, but I'd prefer if the VoD would work again 😉
