Apple releases iOS 8.1.1 with bug fixes, increased stability and performance improvements for iPad 2 and iPhone 4s [Updated]
 
 
 
 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 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.

Let us know if you’ve found any other changes or improvements in iOS 8.1.1 in the comments below.
 
 Update 1:
 
 Updated with direct download links.
 
 Update 2:
 
 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.
 
 Update 4:
 
 Apple  is still signing iOS 8.1, so if you haven’t upgraded yet,  then this  could be your last chance to update to iOS 8.1 and jailbreak  with Pangu.  If you need help on how to update to iOS 8.1 and jailbreak  using Pangu  then check out guides for the step-by-step instructions.
