Apple has released iOS 7.1; update your iThing now
The latest version of Apple's mobile operating system software is out and available for download. To get it, tap "Settings" on the home screen of your iPhone, iPad or iPod touch, then "General," then "Software Update." If your device can run the new software, and doesn't already have it, you'll find instructions there.
Apple has posted a brief rundown of the new features and fixes. Of particular interest to those of us who hold onto our older phones as long as we can is that the new update seems to make them work better. Also of particular interest is that this might be the last iOS update ever for the iPhone 4.
