So what’s new? For one thing, a YouTube channel guide appears when you swipe towards the right from the left edge of the iPhone screen. There are fifteen channels, covering a wide swath of popular types of videos: HowTo & Style, People & Blogs, Science & Technology, etc. Sign in, and your subscribed channels also appear.
You can see the YouTube channel guide by swiping from left to right.
At the moment, the existing YouTube app doesn’t automatically update to the new version, which means you’ll need to look it up in the app store and download it. YouTube says it has an update app for the iPad in the works, but warns fans to expect it “in the coming months.”
