Sure, the iPhone is cool looking, works out a lot, and is really good at math... but it can't do VoIP, can it? Well, yes it can -- and you can, thanks to a company called Fring and a piece of ingenious software (for jailbreakers only). Using the native app, it's now possible to place and receive calls via your WiFi connection, thus making AT&T CEOs cry like little babies. Besides doing Skype and the like, the app also lets you connect for chats via MSN Messenger, ICQ, GTalk, SIP, Twitter, AIM, and Yahoo!, which should make this an attractive package even if you don't want to harness the raw power of IP telephony. You can get the application for free by loading up Installer with the company's repo. Check the video after the break to see the magic happen.

Are you ready to have your brain go flying out of the back of your skull? If you said yes, be prepared to lose your mind... repeatedly. One of the Holy Grails / Seven Wonders of the iPhone World has been loosed upon the Earth today, namely: VoIP. According to a company called Truphone, they have unlocked the secret of IP telephony on the iPhone, and demonstrated said ability today at DEMOfall 07 in San Diego. Executing commands via the Terminal (i.e., on a phone which had been Jailbreak-ed), Truphone CEO James Tagg was able to call another mobile phone using only an IP connection -- all without breaking the SIM lock. According to the company, the software is still in beta, but they soon plan to have a version which will simplify activation, and allow seamless switching between WiFi and SIM use. Clearly, an exciting development for iPhone users, but a cringe-inducing situation for AT&T. Check the video after the break to see it all in action.

Carriers like to throw around the term "unlimited mobile-to-mobile" from time to time, but we don't think this is exactly what they had in mind. ROK's "Viper" VoIP client uses a handset's Bluetooth link to hook it up to a PC sporting a broadband Internet connection, which in turn connects it to any other handset with Viper installed. Better yet, Viper contacts are shown with their availability in a buddy list format -- but the best part? It's all completely free and covers platforms Skype doesn't. Compatibility is limited to a handful of Nokia handsets running S60 right now, but word on the street has ROK releasing on Java and Windows Mobile clients before too long.
