Later today, Apple will release the first fully public distribution of the next version of their mobile operating system, iOS 10. We’ve been using iOS 10 since the early part of the beta period, and it’s been on my “daily driver” phone for a little more than a month at this point. Apple has made a lot of behavioral refinements in this release, but they’ve also made some wholesale changes to the way your iPhone operates.
Our advice: Wait a few days for all your apps to become compatible, but then upgrade if you have an iPhone 5S or later. Maybe Friday?
