News of Apple's next iOS 8 iteration release has brought a lot of excitement among iOS fans as the new update bundle has revamped the music app and Beat 1. However, the jailbreak community will be a worried lot as installing the new update would remove the jailbreak.
There have been speculations that iOS 8.4 is susceptible to jailbreak using the same exploit used by TaiG for the iOS 8.3 untether version, but nothing is concrete as yet.
A jailbreak for the upcoming iOS 8.4 could be possible, unless Apple patches the exploits used in the current jailbreak.
So, if you have jailbroken your iOS 8.1.3-iOS 8.3 device with the TaiG untether update, here's how you should prepare for the iOS release to keep your jailbreak safe.
Ensure that your iOS device is updated with the latest iOS 8.3. Like Apple always does, following the public release of iOS 8.4, expect the signing windows for iOS 8.3 to be closed. You will no longer be able to perform a downgrade to iOS 8.3. So if there is no jailbreak release, then your device would be updated to iOS 8.4 without jailbreak.
Do perform a fresh restore of iOS 8.3, which will last for a long time if there is no jailbreak for the new iOS release.
Most importantly save your SHSH blobs for iOS 8.3 which you could use to perform a downgrade in future.
In March this year, Semaphore, the developer of TinyUmbrella has released an update with a new version allowing users to save SHSH blob from A7 and A8 devices running iOS 8.1.2. Click here for a step-by-step guide for how to save SHSH blob for iPhone, iPad and iPod touch with Tiny Umbrella beta.
