My updates appear to be working again, as is my iTunes sign in. Netflix now downloaded on the iPhone and working in the TV app as expected. Apple's site still shows the iTunes Store having problems with app purchases, so it might still be down for some people, or they just havent' updated the status yet. So far, I'm likeing the TV app. It's a lot easier to browse shows on the iPad than it is on the TV, but not bad there either; superior to the generic search feature if nothing else.
