The jailbreak is very simple, just follow the directions the evad3rs give you through out the entire process. On a side note here is what your going to want to do prior to jailbreaking.
- Backup all of your data on your device using itunes or the cloud.
- Update and Restore your device with iTunes to 6.1, not OTA.
- Turn Off your passcode lock, this can cause issues with the jailbreak.
After you have done this it’s 100% safe to jailbreak. When the jailbreak completes you can then restore from backup to get all your data back. Below are the download links for the iOS 6.X Untethered evasi0n Jailbreak.
