IPHONE JAILBREAK
It's EASY
First, let's talk preparation. If you're working with a fresh, up-to-date device, there's really nothing to it—you're ready to proceed to the next step. If you've already jailbroken your phone once before—especially a 1.1.3 iPhone jailbreak using one of the older methods—then you should restore your iPhone or iPod touch to the latest factory firmware (1.1.4) before continuing. When you restore, tell iTunes that want to set up the restored iPhone as a new phone rather than restoring the settings from the previously jailbroken phone.
Now that you're working with a fresh device, it's time to move on to the easy part: jailbreaking.
Before we begin there are a few essential things to check to ensure that you dont loose any data just incase something goes wrong.
- Install the latest version of iTunes.
- It is adviced to update the device to ios 6.1 .1 .
- Backup the device using iTunes. Its very important.
- Disable the passcode lock from settings if applied.
- Charge your device to at least 50% battery .
