As promised, the latest version of Apple's mobile operating system is now available for download. iOS 9 is yours for the taking, and with it comes an improved Siri, split-screen multitasking on the iPad, those newfangled Live Photos, transit info in Maps, News app and more. All of which will be welcome additions for folks who who didn't get an early peek during the public beta. If the update hasn't already hit your device, you can take a gander at our initial impressions while you wait.
