About iOS 9.3.4 On iPhone And iPad: Should You Upgrade To Jailbreak

Apple has recently made a surprise release of iOS 9.3.4 with no public beta testing when estimated with iOS 3.3.3 rolled out following five betas and almost two months of testing, and it was also widely expected to be the final version of iOS 9 before iOS 10 GM launches in September. But it didn’t, rather the Cupertino-based company has suddenly made available for download iOS 9.3.4 with no warning. Should you upgrade to such unexpected release? Let’s take a walk through now.


The Big Deal

iOS 9.3.4 has one big concern and that is it will affect a number of jailbroken iOS device owners, it patches the recent Pangu Jailbreak solution. The team behind the iOS 9.2-9.3.3 Jailbreak have struggled to jailbreak iOS 9 with their last success coming with iOS 9.1, but later changed when Pangu had a breakthrough with iOS 9.3.3 but Apple has quickly put an end with iOS 9.3.4 release. In fact Apple, even credits “Team Pangu” as the source for this update in its official security notes.

Once updated to iOS 9.3.4, issues arising as the dictionary no longer working and problems with the battery widget freezing etc. According to Apple’s release notes iOS 9.3.4 is all about one vague thing: “iOS 9.3.4 provides an important security update for your iPhone or iPad and is recommended for all users”.

One potentially dangerous exploit, that said is also the exploit Pangu uses for its jailbreaking solution. Furthermore there’s no other important things to consider beyond this. Nothing else included in general performance upgrades, or any new features or refinements added.

Install iOS 9.3.4 on your iPhone or iPad only if you don’t care about jailbreak. iOS 9.3.4 comes out of the blue and appears to be solely about patching Pangu’s recent jailbreak.

If you don’t jailbreak your iPhone, iPad or iPod touch there’s little reason to avoid iOS 9.3.4. Especially as the potential exists for less benevolent hackers to exploit iOS 9.3.3 in the same way Pangu did. Already demonstrated iOS 9.3.4 jailbreak.

Still there are a couple of issues with reports regarding battery widget. If the widget is important to you, steer clear for now as it is likely to be the last iOS update owners of the iPhone 4s, ipad 2, iPad 3 and iPod touch 5th-generation will receive.

With iPhone 7 and iPhone 7 Plus release just around the corner, all focus is on iOS 10 and its major upgrades and new features.
