As YouTube works to incorporate Green Parrot Pictures' software into its system to lessen the shakiness of some user-submitted videos, the new SteadyCam Pro app promises to do the same for videos shot on your iPhone 4

The app accomplishes real-time video processing by pushing your iPhone to its limits. It pulls info from the phone's gyroscopes and accelerometers in order to correct your video as you record. 

So far, reviews have been mixed—some say it's crap, others say it's a neat piece of kit. But, hey, it's free. Download from the Apple App Store to give it a try.
