In case you missed the webcast or it was not playing nice on the day of 5th September, then you are good to catch the full action here. Lumia 920 and Lumia 820 announcement full video during the press event has been posted by Nokia. Animated explanation of details of innovations like PureView and  PureMotion HD display is a must watch. It is a pretty long video so weekend is the best time to watch it for sure if you want to !!
