Qik for iPhone update removed the Wi-Fi only restriction.
So now on, you will be able to share recorded videos over 3G as well.
For those unfamiliar with the App, Applications like Qik enable you to stream videos of entertaining and special moments with your family and friends on Twitter, Facebook, Blogs, etc directly from your mobile phone. Viewers of the Live streaming can send messages to the streamer who will receive those message on his iPhone, allowing an interactive experience on both ends.
Qik update is available via App Store for Free.
