Three different films were made for freephoo, a VoIP telephone app for iPad, iPhone and Android. The films are telling us how the service works, how to use the app and film #3 introduces freephoo for iPhone.
 
Update: The app recently changed to a new design does now listen to the brandname “Plingm”
Anyways…on a related note you haven’t missed “There’s an app for that” right?…
