Livebloggers, rejoice! Justin.TV, one of the world's most popular live video streaming services, has released its new app for the iPhone and iPod touch in the form of an upgrade that enables live video to stream from the device. Both the app and service are free, but the app only works on devices with a camera. Streaming is done over WiFi or 3G, depending on availability.
Thanks to Kristi Evans for the tip!
