iOS 15.7.9 Features

Apple stopped releasing new features for iOS 15 a long time ago and the most recent versions of iOS 15 have all patched up security issues. That hasn’t changed with the release of iOS 15.7.9.

The official change log notes that the update brings an important security fix to iPhone users and you can learn more about it over on Apple’s security site.

iOS 15.7.9 Jailbreak

Developers have released a jailbreak tool that’s compatible with iOS 15 and iOS 16, but it only works with select iPhone models.

The palera1n jailbreak is based on checkm8 and it works with all versions of iOS between iOS 15.0 and iOS 16.2. Currently, it only works with iPhone 8, iPhone 8 Plus, and iPhone X.

What’s Next

It’s unclear if iOS 15.7.9 will be the final version of iOS 15. Apple could choose to push additional versions of iOS 15 later this year, but that hasn’t been confirmed.

The company recently released its new iOS 17 operating system. And while we saw new iOS 16 software arrive alongside new iOS 17 firmware, Apple has yet to release a new version of iOS 15.

Apple won’t push additional iOS 15 upgrades to iPhone 8 and newer going forward. That being said, we could still see new iOS 15 software for the iPhone 6s, iPhone 6s Plus, iPhone 7, iPhone 7 Plus, and iPhone SE down the road.
