The Cupertino-based company always stops signing its previous firmware versions soon after it releases the new update. iOS 8.4 was introduced in July and a lot of users ask the same question ‘Is it possible to downgrade iOS 8.4 to 8.3 or not?’ – so we have the new answer. We shared an instruction on how to do this and now we should share the latest news with you. Does Apple Sign iOS 8.3? The company has stopped doing this. It no longer signs the firmware version. If you are still running this release you might like to learn how to save SHSH blobs for iOS 8.3 because the iPhone maker doesn’t offer these blobs for operating systems it stopped signing. Users who are now running 8.4 firmware can no longer downgrade it. This update has introduced Apple Music service which is not available in 8.3. Hackers managed to find exploits that allow jailbreaking both 8.3 and 8.4 versions. Jailbreak was one of the main reasons why users downgrade to previous firmware version. This is not the case this time. At the same time not all iPhone, iPad and iPod touch users could be happy with iOS 8.4. The next version we’ll see will be iOS 9. Apple already revealed iOS 9 beta 1 and iOS 9 beta 2 testing versions for developers. If you wanted to stay on 8.3 firmware but have already upgraded to iOS 8.4, don’t be upset. Firstly, you get more features and some new options. Secondly, you can still untethered jailbreak your device with TaiG / PP Jailbreak and even customize Cydia since it is available as ‘mobile’ app and not ‘root’ program now. At last but not least, the ‘fruit’ giant will soon offer the public iOS 9 version along with new iPhone models. The next third beta of the future OS should be launched pretty soon.
