You may recall that when iOS 6 came out, it lacked two apps that had been part of iOS from the beginning: Google's Maps and YouTube. Google quickly came out with a YouTube iPhone app to replace the one that went missing, but it received a lot of criticism. And many felt it was a stopgap until a full-fledged universal app could be developed. And happily, Google's free YouTube 1.1 app arrived in the App Store yesterday. It's now a universal app optimized for the screen of the retina iPad as well as the 4-inch screen of the iPhone 5.
