If you have an iPhone, you can now make free VOIP calls over Wi-Fi, thanks to Fring, an application that has been available for devices such as Nokia’s Symbian phones. According to Fring, they are the first “native” mobile VOIP application for the iPhone. This is very handy for iPhone owners who are traveling abroad and want to avoid roaming charges when they make voice calls.
You can download the pre-release version from www.fring.com/fring_is/fringcubator.
