More than half a month after iOS 8.1.1 was officially released, Apple finally stopped verifying iOS 8.1. This means that if you want to restore your iPhone, you can only use iOS 8.1.1. It can't be downgraded to 8.1 or below. Although Apple has closed the verification of 8.1, it does not affect the perfect jailbreak of iOS 8.1.1.
If you have upgraded to iOS 8.1, you can decide whether to upgrade. If you have not upgraded or are currently using a firmware version that cannot be jailbroken, you can only jailbreak by upgrading to iOS 8.1.1.
