Apple has released iOS 9.2.1 (build number: 13D15) for iPhone, iPad and iPod touch to the public, a week after releasing the first beta version of iOS 9.3 to developers.
Apple seeded the first beta of iOS 9.2.1 on December 16, following the second beta finding its way to developers and public testers back on January 4. iOS 9.2, for its part, was a minor update on its own, fixing several behind-the-scenes things, improving performance, and otherwise improving the overall system.
According to the release notes, iOS 9.2.1 contains security updates and bug fixes including a fix for an issue that could prevent the completion of app installation when using a MDM service. So far, the betas have not revealed any major forward-facing changes to the software.
Meanwhile, Apple has also seeded iOS 9.3 to developers and public beta testers, which includes number of new features such as Night Shift, password protected Notes, revamped News app, new 3D Touch Quick Actions and lots more.
Jailbreakers should avoid upgrading their jailbroken device to iOS 9.2.1 as you will lose the jailbreak.
If you don’t care about jailbreaking, then you can install iOS 9.2.1 via OTA update by going to Settings > General > Software Update. The size of the OTA update on the iPhone 6s Plus is 41.1 MB.
