Apple today released iOS 9.2.1 to the public, marking the first update to iOS 9 since iOS 9.2 launched in December of 2015. iOS 9.2.1 has been in testing since December 16, with developers and public beta testers receiving a total of three betas before its public launch.

Today's iOS 9.2.1 release is available as an over-the-air update to all iOS 9 users. A minor update, iOS 9.2.1 is the fifth update to iOS 9 in total, following the launches of iOS 9.0.1, iOS 9.0.2, iOS 9.1, and iOS 9.2.

iOS 9.2.1, as a 9.x.x update, is minor in scale, focusing mainly on under-the-hood performance improvements and bug fixes rather than outward-facing changes. According to Apple's release notes, the update includes security improvements and bug fixes, including a fix for a significant Mobile Device Management issue that affected enterprise customers.
This update contains security updates and bug fixes including a fix for an issue that could prevent the completion of app installation when using an MDM server.
iOS 9.2.1 will be followed by iOS 9.3, which has also been seeded to developers for testing purposes. Set to be released in the spring, iOS 9.3 is a major update that introduces a new Night Shift feature to cut down on blue light exposure during the evening for better sleep and brings new educational features.

iOS 9.3 also includes new Quick Actions for iPhone 6s users and it introduces updates for apps and features like Apple News, Notes, Health, Siri, CarPlay, and More.

I find myself thinking about these programmers who spend 8+ hours every day of their working lives creating these performance improvement and bug fixing updates which are provided free of charge, quickly distributed, and sometimes never even noticed by consumers...and yet I'm just sad I have to wait even longer for Night Shift :(

family calling me complaining about how they dont have enough space on their devices to get rid of "that annoying red 1" in 3 ... 2 ... 1 ...
Doesn't seem likely with this update, unless they already don't have pretty much any free space to begin with (which is its own separate issue in a sense).

How to do it my friend?
It's possible to restore to iOS 9.2.1 however once the iCloud back ups your new device it sometimes looses the older back ups and the new back up is no longer capatible with iOS 9.2.1. I've tried my self spent the whole weekend doing it and tried instead of restoring to iOS 9.3 using the update method. I pressed option on my Mac and clicked update in order so iTunes would give me the option to choose the file and it did however once the device was back to iOS 9.2.1 I was no longer able to see any my apps. they were installed since my device had memory missing. I reseted settings with no luck. So I just stuck with iOS 9.3 in order to keep my recent back up.
