Apple yesterday released iOS 9.1 beta 5 to developers and public beta testers, just a week after the fourth beta was given to developers, BGR reports.
The new iOS 9.1 beta 5 contains bug fixes and improvements currently available to iOS developers and those who have access to public betas. Known issues listed in the full release notes include iCloud Keychain setup error, PhotoKit issues, and iCloud backup restoration problems.
The tech giant seems to be in a rush to push out the official iOS 9.1 to the public, perhaps in the hope of putting an end to bugs that were not addressed by iOS 9.0.1 and 9.0.2. In fact, according to Forbes, Apple has already broken records of the fastest rate beta builds are released. The beta build is now at the fifth version just 33 days after the first one. Historically, it took twice that amount of time.
While it's good to get the fixes to the users as soon as possible, there is a risk that the supposedly fixes also bring in additional problems. This is what actually happened with the iOS 9.0.1 and iOS 9.0.2 -- broken notifications, hanging emails, iMessage problems, Signing issue. Hopefully, the new builds would really address the issues and will not add another bug to the list. If so, Apple would deserve a praise for getting issues fixed in the fastest time possible.
If the Signing issue has been addressed (it prevented you to go back to previous iOS version) and you want to downgrade to iOS 8.4.1 until the official iOS 9.1 has been released to the public, follow the instructions here.
In other news, Lifehacker reported that the iOS 9 jailbreak is now available and the tool can be downloaded here. Lifehacker has advised though to hold off for a while until most tweaks and apps are updated.
