I highly recommend JanusVM for your iPhone VPN solution. Janus incorporates squid, tor, and privoxy providing much more than just a VPN. Squid is a proxy server, which will speed up your connection slightly. Tor is a network of servers around the world that will scramble your network traffic so its practically impossible to track who or where you are. And privoxy will strip all sensitive data from your website browsing to further improve your wireless security. Obviously the VPN part of Janus will allow your iPhone to have a secure connection to the internet, so you can access wifi anywhere without fear of anything!!! The best part is JanusVM is that it’s completely free. I highly recommend donating a little money if you have it. The author of the software is providing a great service to the open source community, and now allows iPhone users to have a secure, reliable, and instant VPN solution! http://janusvm.peertech.org/ Just pop JanusVM into a VirtualBox machine, and setup host networking to grab an external ip address. Configure your iphone to access your external ip address, the associated pptp port (port 1723), and viola your VPN should be up and running in about 15 minutes worth of configuration :) In the future I will post a graphical tutorial on this, but for now try searching this blog, in the upper right hand corner, for more information about setting up virtual machines and configuring host networking.
