Who needs a new iPhone? iOS 12 adds tools and features to freshen up your current device

Apple's new iPhones will understandably grab the spotlight at the company's media shindig Wednesday at its Cupertino headquarters. But no less important for iPhone (and iPad) owners who have no intention of dashing off for the latest models, will be the official release of iOS 12. It is the software at the core of these devices that promises to freshen them up with new features and tools, including possibly adding zing to an aging handset, even one as old as the iPhone 5S. That means you should be able to install iOS 12 (which you can do for free) soon after Apple's press event. Just be aware that some of the features arriving with the latest software will require or work better on more recent hardware.
