How to un-jailbreak

Hi I have an appointment at the genius bar. How do I un-jailbreak my device without leaving any traces of jailbreak?

Just restore your phone through Itunes

Un-Jailbreaking:
If you had already jailbroken your device and didn't like this style, you can switch back and un-jailbreak your device easily

Note: This guide only applies to software versions 3.1.3 for the iPhone and iPod Touch, and 3.2 for the iPad.


Step 1: You need is your device's latest firmware file that can be got from here.
Step 2: Plug your device in, and open iTunes
Step 3: Shift-click (Windows) or Option-click the "Restore" button in your iTunes device summary page. Navigate to the firmware you've downloaded, and restore.
Step 4: Now iTunes should ask you if you want to set up your device as a new device, or from a previously stored backup. If your goal is to return to a life before jailbreak, you're probably going to want to restore.
