Our Mobile App of the Day today is Justin.tv Live Streaming Video. Justin.tv is a site that allows users to share videos and live stream events using your Justin.tv account. While the app has been available for Android since September 1st, today is the first day it has been available as an iPhone app.

Video quality for both apps have been optimized for 3G and WiFi connections and quality is set up to adjust as the phone is moved to minimize stuttering. Users can watch your streams as they happen and make comments in a chat overlay that does not require a different screen as the stream. iPhone 4 users can switch between front and rear facing cameras if they wish. Have the need to share what you're doing as it happens? Grab the app for Android or iPhone for free.
