Apple has just released their latest update to iOS 9, iOS 9.2.1. This update is available for iPhones, iPads and the iPod Touch and is available right now. This update builds off of the last update, iOS 9.2, which was released just last month.
This update pertains mostly to enterprises specifically and offers no new features; it’s fixing problems that have been reported by their mobile device management users. While Apple says that the update is fixing a security bug, they are not specific about what the security issue they are fixing contains other than that is could prevent the completion of app installation and download.
A beta version of iOS 9.2.1 was released to developers on December 16, just one week after the release of iOS 9.2. According to Andrew Cunningham for Ars Technica, Apple has communicated that there are a few other things that they are in the process of fixing.
“Last week, Apple acknowledged a time zone-related bug in the iPhone 6S and 6S Plus that could keep the battery percentage indicator from updating properly when users manually change the time zone or travel from one time zone to another. We’ve asked Apple whether iOS 9.2.1 includes a fix for that issue, but in the meantime Apple’s support document provides an official workaround. We’ll update this article if the company responds and if the update fixes any high-profile security issues (the notes about specific security fixes post to this page and generally take an hour or two to show up).”
Full details on what is included in the iOS 9.2.1 security update can be found here.
iOS 9 supports the iPhone 4S or newer, the iPad 2 or newer, the iPad Mini, iPad Pro and 5th or newer generations of the iPod Touch.
