You will need to down load the "fring" app. If you haven't already done so, you will need to download the SIP service. VoIP Buster is the free avenue for making international calls, but you can not call the UK. If you are in the UK, you will need to go through VoIP Stunt. Click on your perspective link on the left hand side. You will need to register. Launch iPod Touch. Touch More, Add-ons, and SIP.
