Despite Apple Inc.'s efforts to tighten the software security features of its mobile operating system, it seems like the prolific jailbreak teams can still penetrate their system and will launch the next iOS 9.1 jailbreak in the coming days.

Numerous reports said that hacking groups like Team Pangu and TaiG are busy developing the next jailbreak tool that will work on the latest iOS 9 updates, including the iOS 9.1 and iOS 9.2.

Gospel Herald reported that Pangu has launched the semi-jailbreak online script for iOS 9.1. However, it is only available online as of now, and the semi-jailbreak tool is not yet fully functional.

Because of its incomplete components, most jailbreak tool users still opt to stay away from the semi-jailbreak tool because it can damage their devices. Once they choose to download this tool, they can no longer downgrade to a lower iOS 9 version after Apple Inc. disabled the downgrading options. This means that they will be stuck with the semi-jailbreak tool until the iOS 9.2 comes out.

Meanwhile, N4BB reported that an iOS 9.1 jailbreak tool already exists. However, the report mentioned that the tool is not available to the public.

According to the report, a cybersecurity firm Zerodium launced a $1 million bounty for any hacking team that can jailbreak iOS 9.1. But the requirements to get the reward said that the tool must be browser based so it can be applicable to all types of iOS devices.

A jailbreak team reportedly submitted its tool to Zerodium and received the reward money. The undisclosed team reportedly managed to come up with a working, browser-based untethered jailbreak that can work on both beta versions of the iOS 9.1 and iOS 9.2. But since Zerodium already owns the license for the jailbreak tool, it can no longer be released to the public.

Still, some reports claim that other jailbreak teams can still come up with their own iOS 9.1 or iOS 9.2 jailbreak tools and release it before the end of 2015 or early 2016.
