It's just over a month past the launch of iOS 8, and the first major iteration has just been released for iPhones and iPads. So, what's new in iOS 8.1? Without a doubt, the biggest addition is Apple Pay. Finally, you can use a combination of NFC and Touch ID to make payments on the App Store, and at select retail locations. In addition, this update brings a handful of other useful improvements to both the Messages and Photos apps.
