3G2 is a video format developed by the Third Generation Partnership Project specifically for 3G (third generation) mobile phones. Because the internet speed on cell phones is slower than most home internet connections, 3G2 videos are highly compressed and are usually lower resolution that videos you would normally watch on your computer.
