iOS 8 Jailbreak: How to backup and restore Cydia apps, tweaks and sources on your iPhone or iPad
iOS 8.1.3 release imminent: How to preserve existing jailbreak tweaks and apps

The internet is abuzz with news of an impending iOS 8.1.3 release in the next few days, as Apple's testing process for the next iOS update intensifies with the recent iOS 8.1.3 beta version rolling out to the company's retail employees.

Prospective jailbreakers are advised to capitalise on this opportunity to update or restore their device back to iOS 8.1.2, as it is the last chance to install the latest iOS version supporting TaiG jailbreak (for Mac and Windows) and PP jailbreak (for Mac only).

iOS 7.x.x Users

Those running iOS 7.0.x can be assured that the iOS 8.1.2 update is highly-stable and there are loads of bug-fixes and improvements ported into it. Besides several compatibility issues with a number of jailbreak tweaks have also been fixed in iOS 8.1.2.

iOS 8.1.2 OTA and iOS 8.0.x

iOS 8 users who have recently updated to iOS 8.1.2 via OTA are advised to restore it again via iTunes, before applying the latest TaiG or PP jailbreak as OTA updates have known compatibility issues with jailbreaking.

Meanwhile, those who are already jailbroken on iOS 8.0.x are required to upgrade to iOS 8.1.2 and re-jailbreak the device in order to install the latest jailbreak tweaks and apps on the device.
