5 Things to Know About the iOS 17.1.2 Update

Apple’s pushed a new iOS 17.1.2 update to iPhone users ahead of a much larger iOS 17.2 update coming later this year.

If you own an iPhone that’s compatible with iOS 17, you can download the iOS 17.1.2 update on your device right now. Head to the Settings app and check for the upgrade.

Like its predecessor, iOS 17.1.2 is a maintenance update and it delivers under-the-hood improvements to iOS 17-powered iPhone models.

While it’s a small upgrade, it’s an important one, and most iPhone users should download the software today or sometime in the near future.

Today we want to take you through iOS 17.1.2’s changes, offer some thoughts about the software’s performance, highlight iOS 17.1.2 problems, and more.

We’ll start with a quick look at iOS 17.1.2’s performance.

iOS 17.1.2 Review

If your iPhone is currently running iOS 17.1.1, you’ll see the smallest download size. iOS 17.1.2 is a 300MB download for iPhone 12 Pro and it should be in and around the same size for other iPhone models.

The iOS 17.1.2 download depends on your iPhone model and the version of iOS it’s currently running. If you’re running software older than iOS 17.1.1, your download could be much larger.

As for the installation, it took about eight minutes to complete on an iPhone 12 Pro that was previous running iOS 17.1.1. If your iPhone is running older software, it could take longer.

iOS 17.1.2: What’s New

Apple’s point updates (iOS x.x.x) typically focus on fixing problems within the operating system. And that’s precisely what iOS 17.1.2’s focused on.

The company doesn’t list any bug fixes or features in the change log. iOS 17.1.2 is instead focused on patching up security issues within the operating system.

Apple says the software addresses two vulnerabilities that may have been exploited against versions of iOS before iOS 16.7.1.

For more about those changes, head over to Apple’s security site.

iOS 17.1.2 Jailbreak

If you still jailbreak your iPhone, make sure you avoid the iOS 17.1.2 update

We don’t expect developers to release a public jailbreak tool that’s compatible with iOS 17, or iOS 17.1.2, today. If you still jailbreak your iPhone(s), keep an eye out for new information in the weeks ahead.

What’s Next

Apple’s currently working on a new iOS 17.2 update and the software will arrive in December ahead of the holidays.

If you can’t or don’t want to wait that long, you can download a pre-release version of iOS 17.2 onto your iPhone via Apple’s beta program.
