In iOS 9.1, Apple has blocked several vulnerabilities. Among them were those that were used to create the iOS 9 jailbreak. However, hackers from the Pangu team have already found new vulnerabilities.
According to reports, hackers are now working on a new jailbreak. However, the release of the utility will take place after the release of the final version of iOS 9.2. More specific dates are currently unknown. It is also worth noting that the hackers will first release a Windows version of their utility.
In general, the decision to wait until the final version of iOS 9.2 is released is justified. If hackers release the jailbreak earlier, Apple will be able to find and fix new vulnerabilities in one of the beta versions of the firmware.
