It might not have been ready for launch day, but Netflix has just released an update to its iOS app with optimizations for iOS 6 and the iPhone 5. When Apple announced that its latest handset (and iPod touch) would contain a 4-inch Retina display, the company highlighted video as one of the taller screen's key advantages. Users would be able to watch movies using the industry standard 16:9 aspect ratio without any letterboxing or black bars, and now that luxury has arrived for Netflix subscribers. Other than the improved video experience, not much about the app itself has changed; it still utilizes the simplified player interface introduced back in May, though we have no complaints about usability. The latest version of Netflix for iOS is available in the App Store now.
