The new Qik iPhone application, Qik Live, can finally stream live video over a 3G connection. Now there is no need to use the built in YouTube upload function that comes with your iPhone.
A bonus to using the Qik Live app is that it will work on any version of the iPhone, not just the 3GS model. The Qik Live iPhone application can save and upload video to any social networking site, such as Twitter or Facebook.
