Things to Do Before Installing iOS 9.2.1

If you do decide to download the iPhone 4s iOS 9.2.1 update, you'll want to prepare. 

It's difficult to predict how your iPhone 4s will react to the iOS 9.2.1 upgrade so you'll want to make sure your files are backed up, that you've checked in with IT (if you have a department) and that you've read reviews of apps and services. 

We've put together a guide that takes you through the pre-installation process we use for every single iOS update. Some of these steps will take you a few seconds, others will take a few minutes of your time. All of them should help.

This might seem like overkill but you'll want to be as prepared as possible, especially if you're coming from an update that's older than iOS 9.2. There's no going back to iOS 8 or iOS 7 once you make your move.

    Some users are actually experiencing the placebo effect. Not performance improvements. I have noticed nothing at all. I bet not one ounce of time ever went into any performance fixes.

      I would imagine you’re right seeing as you can’t measure time in weight, lol.
