Fring, fring: VoIP calling the iPhone
Voice over IP client Fring has released a version of the application for the iPhone, effectively giving users of the Apple device free phone calls.
However, would-be users will have to unlock their iPhone to use it, and may need to be in range of Wi-Fi hotspots to get the most out of the application.
Fring integrates with different VoIP clients, including Skype, MSN, Google pTalk and AIM, allowing users to access them all through a single interface. The application is already available for devices running Series 60 and Windows Mobile. Fring uses its own protocol, which was created with mobile use in mind, circumventing any problems in getting the various VoIP applications' protocols to work on mobile networks.
