For all of you out there that have an iPhone or any other mobile "idevice" And want VPN access I have found a way. The catch is, you have to have a jail broken device. If you do have a jail broken device and want the openvpn app on the phone you will want to check out www.guizmovpn.com it's about 4€. The evaluation period is a full week. But the price is worth it.
To configure the client you will need to follow the guide on the www.guizmovpn.com. The client info you will need to get from the wiki here http://wiki.amahi.org/index.php/VPNLinux also you will need to hit the FAQ on guizmovpn to setup the login info for your hda.
If your interested and want some help setting it up let me know. Once I'm back from vacation I will setup have also created a small full guide for setting it up with everything you will need custom tailored to knowamahi vpn access. For anyone that is interested i have provided a link to a pdf guide i created. It might seem like a little to much or a hassle but its really simple. It just takes the time to read. http://home.mchsi.com/~irish-link/GuizmOVPN.pdf
My mind is a little random some times, so if you do want to set yourself up and have problems or any other issues with the guide let me know and i will do my best to clarify. If you do end up setting it up, let me know how it works for you.
NOTE I can now verify that it does in fact work with Jailbroken IOS4.
NOTE: The "credentials.txt" is not needed anymore (since 0.9.8).
Simply replace "auth-user-pass credentials.txt" by "auth-user-pass", and you'll get prompt for username/password on connection.
The pass-file is still supported, but the prompt makes more sense for security...
