Apple has changed their online article surrounding the dangers of jailbreaking after the evasi0n jailbreak that allowed users on iOS 6.0 and 6.1 to jailbreak their device. The tool arrived on Monday, and Apple’s article was modified on Sunday when the jailbreak was supposed to go live.
Apple talks about how jailbreaking can make your device unstable, reduce your battery life, leave you open to security vulnerabilities and disrupt services.
Apple is unable to prevent users from jailbreaking – it has been ruled legal by the U.S. Copyright Office. However they can terminate support for the device and can make it a violation of their EULA (which they have).
Jailbreaking allows users to install applications without going through the App Store. You also have more access to the system files, which allows you to do things like ‘skin’ your device to have a certain theme, changing the colors and more. You can also disable apps that are included with the device like NewsStand and others. Although useful for some, it can be problematic – most of what Apple says are true – if you install rogue apps, they can access personal information and poorly written apps can quickly drain battery life.
