As far as one looks, the idea of plagiarism has been around for quite some while now. In terms of iOS, Apple’s proprietary platform for its cellular devices since 2007, “Jailbreaking” has been around as well. What Jailbreaking allows is to patch the kernel of the device in order to move around the operating systems, dodging Apple’s software restriction, which by the way, are plenty.
While back in the day, Jailbreaking was quite common and easy. Selling carrier locked phones on Ebay was quite common because, with Jailbreaking, people could use any sim card on those devices. This meant that users didn’t have to pay full price for the unlocked version. It also meant that illegal phone trading, selling stolen devices had become quite common. Lately, Apple has taken many steps to move around this issue. Even Apple’s input devices today are MFI certified. Jailbreaking is the key around these as well.
Apple has been patching its iOS version for a while now to limit and stop developers and hackers from directly getting to have root access to the device. While steps are taken to infuse the core software, services like iCloud lock prevent stolen phones from being sold and used. Apple patches its software to stop jailbreaking but for some odd reason, for iOS 12.4, the company just missed it. Having introduced and highlighted in iOS 12.3, the previous version, it meant that hackers could not simply get into the device (of course there were exceptions). Today, though, the company pushed iOS version 12.4.1. In the minor update, Apple has patched the security vulnerability that was left open for hackers in the previous version. The update is available for OTA download and it is advised that users should do so as soon as possible.
