Downloading an iOS update is like getting a haircut or taking out life insurance; you’ll get to it eventually. The security fixes in iOS 9.2.1, though, available as of this week, earn it a place at the top of your to-do list.
“This is the longest it has taken Apple to fix a security issue reported by us. It is important to note that the fix was more complicated than one would imagine,” wrote Skycure CTO Yair Amit in a post announcing the fix. “However, as always, Apple was very receptive and responsive to ensure the security of iOS users.” Important, too, is that despite lurking for so long, this attack was never spotted in the wild.
One hiccup that iOS 9.2.1 doesn’t address? A problem with the battery percentage indicator that’s been a minor annoyance to some iPhone 6S and 6S Plus owners. Still, best not to wait for that fix to come around before going through the install process. All these security fixes may be under the hood, but they’re important for your safety—especially now that the vulnerabilities they patch up are all public knowledge.
