An iOS 7 update released recently aimed to destroy the Pangu jailbreak, a tool that makes untethered jailbreaking possible with Mac or Windows.

The update also came with major fixes and some tweaks, sans the removal of the Pangu tool.

Jailbreaking is where users modify Apple's iOS, so that it gives full system access, allowing installation of apps which are normally not possible unless done through iTunes App Store.

Among the restrictions Apple implements in its OS, the company does not support jailbreaking, and applies penalties for any such violations, which usually involves voiding the owner's warranty.

The Pangu jailbreak came out when hackers tried to decipher iOS 7. It was originally released in Chinese but now has an English version as well.

According to Cult of Mac, using Pangu is pretty straightforward, walking the user through the entire process. It requires adjusting the device date to June 2 and turning off the option "Set Automatically" (something advanced users should be familiar with).

That iOS 7.1 Pangu allows untethered jailbreaking means it does not require the device to be connected to the computer when running the jailbreak application.

Pangu was first released only for Windows, but is now expanding to iOS and Mac OS X. It already works on both iOS 7.1 and 7.1.2.

With Pangu's expansion to Apple's operating systems, and with the English version, the jailbreaking tool has intrigued  jailbreaker Stefan Esser (a.k.a. "i0n1c"), who claims it stole some of his ideas, and calls its developers "thieves."

Esser sends his regards to those who installed Pangu to have fun with the possible malware threat from China.

Another jailbreaker, "Ih8sn0w," said there are no malicious trails in the Pangu tool. Still, users are warned to apply precautionary measures to ensure their data and system protection.
