Good news and bad news. First the good news: the free NBC Olympics Live Extra app will be offering live streaming video of all 32 athletic competitions to your iPhone or iPad. The bad news: the app requires that you already be subscribed to cable or satellite service to access most of the live streaming. Early reviews also criticize it for only offering portrait view for video. Apparently there will be some limited live streaming even if you don't subscribe to a service.
