How to Unjailbreak an iPhone


Jailbreaking your iPhone allows you to use the device with any GSM mobile carrier. To switch carriers, all you need to do is swap one mobile carrier's SIM card for another. However, jailbreaking can have unintended consequences. If you have noticed that your iPhone is running slower than usual or freezing up, it may be the result of the phone being jailbroken. Fortunately, the process is reversible. You can unjailbreak an iPhone quite easily by using the Restore utility in iTunes.

  • Connect the jailbroken iPhone to your computer using the phone's USB cable.

  • Launch iTunes if it does not open automatically.

  • Click the "iPhone" icon under "Devices" in the left pane of the iTunes application window.

  • Click the "Summary" tab, then click the "Restore" button.

  • Select "Back Up" on the pop-up window to have iTunes back up the settings on your phone. Itunes performs the backup.

  • Click the "Restore" button on the confirmation pop-up window. The restore process begins on your iPhone.

  • Click "OK" in the pop-up window. The iPhone restarts and displays the "Connect to iTunes" screen. The "iPhone is Activated" screen then opens. The "Set Up Your iPhone" page opens in the iTunes window.

  • Click the check box for "Restore from the backup of" and select the iPhone backup archive you previously created.

  • Click the "Continue" button. The iPhone has been restored to its previous state before it was jailbroken.

Tips & Warnings

  • Before you attempt to reverse the jailbroken status of your iPhone, download and install the latest version of iTunes if you don't already have it.
