    Apple has stopped signing iOS 8.4 for compatible iPhone, iPad and iPod touch models, meaning that users can no longer upgrade or downgrade to that version using iTunes. Apple is now signing iOS 8.4.1 and later only.

    iPhone, iPad or iPod touch users that have jailbroken their device on iOS 8.4 should refrain from updating to iOS 8.4.1, as the latest software update breaks the iOS 8.4 untethered jailbreak released in June by Chinese hacking team TaiG.

    Chinese team Pangu demonstrated an iOS 8.4.1 untethered jailbreak (via iPhoneHacks) at the HackPwn2015 security conference last week, but the method has not been publicly released. With the public release of iOS 9 expected in less than a month, it is possible the team may hold off on exposing an exploit to Apple for a minor software update.

    Is it that hard for Apple to make the iPhone unjailbreakable?

    In between a rock and a hard place
    Some would hope that's exactly the case.

    Would you feel better about it if it were American software?

    Yeah putting software written by Chinese hackers on your phone doesn't seem to be the smartest thing. For all we know, Pangu could be composed of hackers working for the Chinese government.

    Well, seeing how my iPhone is already running American software as is any Windows or Android device, the answer is yes.

    Not all Chinese software is spyware or malware. I have my iPod touch jailbroken with TaiG on iOS 8.4 and everything has been fine.

    Yeah, it's so weird to put Chinese software on a phone that's made there with pars from all over the world...

    Are you sure that all your software originates in the US? Including all the apps you run? Do you check each time whether the developer is not Chinese?

    Of course not, you install the software because you trust the origin. You trust Apple, you trust the App Store. You don’t trust obscure programs from random sources on the web whether they come from China or not (it is also easy to setup servers in the US, by the way). Jailbreaks are exploits and notoriously secretive and you can thus never be sure that you are not putting yourself at risk. No need to start becoming suspicious only because these hackers happen to operate from China. The developers of other jailbreaks are even more difficult to track.

    This is rather unfortunate but it's not something I didn't see coming.

    8.4.1 was constantly locking up my Music app and anything I would do with my Apple ID in Settings on my iPhone 6. A reboot would fix it for a couple of hours until it prompted me to sign up for Apple Music again. If I attempted to sign up again it would lock up and any request to View my Apple ID would cause it to time out. I did a fresh install of 8.4.1 and it still happens, though not nearly as frequently.

    I posted on Apple's support forums only to get similar responses.

    I'm having this issue on my iPhone 6 too. It's very annoying rebooting my phone multiple times a day just to keep it functioning properly.

    Well, every iPhone that has been mass produced has been assembled in China. If we wanted to be really paranoid, we could worry that the Chinese could be installing something in the phones during assembly that allows them to silently hack into the device at the hardware level.

    No, they can query the phone and refuse to install any apps from Itunes or the App store if the phone is not set to factory default. Btw- this is the same thing the PS4 does - unless you update your console, you cannot play anything on it.

    The question is would it be worth it to annoy the 5-10% of people who jailbreak? after all, these are paying customers as well.

    WAIT, does this mean that it was still possible to upgrade to 8.4 even with 8.4.1 available up until yesterday?

    Yes - the window is usually open for 1-2 weeks after a new release

    For next time, bookmark this site which has a live status of what firmware are currently being signed:

    Dammit, did not know that, wish I had..., haha!! so now its too late, blehh!
    I gotta admit, the only reason I didn't do anything is cause I needed to backup my phone first (haven't since I got it, so over a year), and needed space on my computer to do it to then upgrade,and finally got enough space, lol...
    So, I'm still iOS 7.0.x, should I update, lol?

    Only update if you like having a secure phone. Otherwise feel free to use IOS 7.

    No. I suspect that they keep a sliver of a window open for jailbreaking to keep the xx% of jailbreakers in the iOS fold. If they couldn't jailbreak some/many/most/all would switch to Android.

    Only update if you want to turn your phone into a secure slug. Otherwise continue to enjoy using iOS 7.

    nah wait a few more weeks and just do iOS 9 then. It should work better than 8 anyway.

    I like the idea behind jailbreaking but it never satisfied me with offering other ways of securing my phone. I couldn't justify adding another attack vector to my iDevice just for the sake of a few more wallpapers or whatever it is JB's offer these days.

    They did something to the ATV 3 which makes it unbreakable, which is why the ATV2 is more valuable on ebay. Clearly there is something they can do, but I assume they are holding back for some reason. Can anyone shed additional light (spotlight maybe...:D)
