Apple has just released iOS 8.1.1 (build number: 12B435) for iPhone, iPad and iPod touch. Apple had seeded iOS 8.1.1 beta to developers two weeks back.

According to the release notes iOS 8.1.1 includes number of bug fixes and brings improved stability. According to Apple, iOS 8.1.1 also includes performance improvements for iPad 2 and iPhone 4s, but a video comparison of iPhone 4s running on iOS 8.1 and iOS 8.1.1 did not reveal any major improvements on older iOS devices.

This release includes bug fixes, increased stability and performance improvements for iPad 2 and iPhone 4s.

iOS 8.1.1 release notes

iOS 8.1.1 is compatible with the following iOS devices:

  • iPhone 4S, iPhone 5, iPhone 5c, iPhone 5s, iPhone 6, iPhone 6 Plus
  • iPad Air 2, iPad mini 3, iPad 2, iPad (third-generation), iPad (fourth-generation), iPad Air, iPad mini, iPad mini with Retina display
  • iPod touch 5G

Jailbreakers should avoid upgrading to iOS 8.1.1 as it kills the Pangu iOS 8.0.x-iOS 8.1 jailbreak. Apple seems to have fixed at least one exploit used by the Pangu jailbreak, so you won’t be able to jailbreak your device using Pangu after upgrading to iOS 8.1.1.

If you don’t care about jailbreaking, then the update is available as an OTA download for these devices currently. The OTA update is 64.7 MB for iPhone 6 Plus.

If you’re not getting the OTA update, then you can download the iOS 8.1.1 ipsw (firmware file) using the direct download links provided below. If you need help then check out our guide, which shows you how to install the iOS 8.1.1 update on your iPhone, iPad or iPod touch.

Some users are reporting that after installing the update, they were prompted to log back into iCloud (which was requested previously), and also review iMessage settings, which wasn’t required previously.

Update 3:

Jailbreakers should avoid the iOS 8.1.1 update as Apple has patched at least one of the exploit used by Pangu jailbreak, so iOS 8.1.1 kills Pangu jailbreak.
