If you need to undo your jailbreak, follow these simple steps to restore your iDevice to its original (jailed) state.
Jailbreaking isn't for everyone. Cydia is quick to overwhelm even the tech-savvy user, and upgrading iOS software on a jailbroken device can be a headache-inducing process.
Whether you've discovered that jailbreaking isn't for you, or you need to take your iDevice to the Genius Bar for repair, you'll need to unjailbreak your device.
There are plenty of forums, blog posts, and YouTube videos that attempt to guide you through this process. Many are outdated, and, in some cases, incorrect.
So, to find the proper way to unjailbreak an iDevice, I went to the source. Nikias Bassen, a developer for the Chronic-Dev team, the folks behind the Absinthe jailbreak and greenpois0n.com, offered this simple solution:
In a few minutes, your device will restart, and your apps, settings, and other data (like contacts) will be restored. Cydia is gone, and when you take your iDevice to the Genius Bar, there will be no obvious traces that you once broke your gadget out of jail.
