Apple ceases signing iOS 8.1

Apple has stopped signing iOS 8.1 on compatible hardware, including iPhone, iPad and iPod touch. This means that, after you upgrade to 8.1.1, you can no longer downgrade back to 8.1.

Typically, a short time after a new version of iOS comes out, Apple stops signing the previous one. If you're not familiar with the signing process, after you install a new version of iOS, it checks with Apple's servers to make sure that it's an authentic copy and hasn't been tampered with or modified in any way. That prevents, for example, people being tricked into installing an older version with known security exploits, or an altered, malicious version.

Since iOS 8.1.1 includes numerous bug fixes and performance enhancements, there should be few if any reasons for anyone to want to downgrade anyway.

In fact, if you haven't upgraded to iOS 8 at all yet, iOS 8.1.1 is likely the version you've been waiting for.

  • It has drastically improved my iPod Touch 5. It's incredibly smooth even with reduce motion off, and before even on iOS 8.1 having it off kinda caused some lag here and there and with iOS 8.1.1 it's even smooth with it off. For those jailbreak users there already is a jailbreak for iOS 8.1.1 and it works flawlessly, it's not by Pangu but by another Chinese group but even then it works good Posted via the iMore App for Android
