It is reported that jailbreaker Luca Todesco has finally jailbroken iOS 8.4.1 but it is available only to the users of iPhone, iPad and iPod touch, who haven't upgraded to iOS 9.
Apple has introduced "rootless" technology to iOS 9 -- blocking access to iOS root to prevent hackers from jailbreaking – and it seems to be working, as wellknown hackers haven't managed to sneak through.
TaiG, Pangu and other jailbreakers seem to be finding hard to jailbreak the firmware.
iH8sn0w, developer of popular jailbreak tools such as Sn0wbreeze, P0sixspwn and iFaith, had earlier released a video showing an untethered iPhone 5 running a jailbroken iOS 9 on his YouTube channel but it's not heard off since then.
The only option to jailbreak iOS 9 at the moment is Semi JB's partial jailbreak but here too one can only install the Cydia with limited functions.
Interestingly, Apple has released upgraded versions of iOS 9 -- 9.0.1 and 9.0.2 – and fixed almost all the known exploits. In fact, iOS 9.0.2 came with several bug fixes like cellular data usage switch, iMessage activation, iCloud backup, screen rotation, Safari browser, Photo apps and custom APN setup.
So, there is a possibility of jailbreakers jumping to iOS 9.0.2 jailbreak instead of working on its earlier versions.
It may be mentioned that security firm Zerodium has put out a huge bounty called "The Million Dollar iOS 9 Bug Bounty" for individuals and organisations who can jailbreak iOS 9. It has offered $1 million each to three researchers ($3 million in total) who come up with iOS 9 jailbreak on Apple's iPhones and iPads. [READ: The Million Dollar iOS 9 Bug Bounty programme]
