My Nexus has informed me that it has downloaded Android 4.2.2. and that I can install it, but I'm holding off until I know it is 'safe', by which I mean will all my apps still work? I ask, because when my brother bought his Nexus a few months ago and was bumper up to 4.2.1, iPlay stopped working for a while. So I'm prepared to wait with the upgrade until word comes through that other apps will not stop working. Any thoughts?
