How to UnJailbreak the iPhone 4S

If you want to take your iPhone 4S back to stock, there are a number of ways to unjailbreak the iPhone 4S, but this is the easiest and quickest way to restore your iPhone 4S.

There are a number of reasons you might want to unjailbreak your iPhone 4S, but the most common reasons are to take your iPhone into Apple for service and to speed up your iPhone 4S if your jailbreak apps have slowed down your phone.

The unjailbreak process is straightforward, and allows you to go back to stock very quickly. This method will also allow you to make sure that your iPhone 4S stays on iOS 5.0.1 when it updates, even after Apple releases iOS 5.1 or iOS 5.0.2, both of which will take away your ability to jailbreak the iPhone 4S again. At least until the dream team releases another round of tools.
