Get ready for free VoIP calls on your iPhone. An Israeli company called Fring announced today that it started publicly testing an application for the iPhone called Fring which allows users to make and receive calls using voice over IP technology. In case there’s any sort of misconception here, Fring bypasses any cellphone carrier and relies solely on an Internet connection to make a call.

But here’s the surprise. Fring allows users to make VoIP calls over 3G or EDGE connections, which is a huge deal. With Fring, all customers need would be a data subscription with their carrier (in case of the U.S., AT&T) and begin making those free calls. According to Fring, the application will dynamically adjust audio quality depending on the type of connection it detects.
