If your interested and want some help setting it up let me know. Once I'm back from vacation I will setup a small guide for setting it up with everything you will need to know.
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...
