This afternoon iOS 8.1 launched for the iPhone 5, the iPhone 5s, iPad, and basically every device from the past couple of years. We know what iOS 8.1 means for the iPhone 6 and iPhone 6 Plus, but what about the iPhone you have in your hand right now? What if you DIDN’T just go out and purchase a new iPhone this generation? What features do you get from this download if you've got previous-generation hardware without NFC? No Apple Pay for you, for starters.
