How to jailbreak iOS 6.0-6.1.2 untethered on all devices

All devices can be jailbroken on iOS 6.0, 6.0.1, 6.0.2, 6.1, 6.1.1, and 6.1.2. The evasi0n tool can be downloaded from its official website at evasi0n.com. Here are detailed instructions for using evasi0n:

1. Make sure you have the latest version of iTunes installed (it includes drivers that help your computer communicate with your device).
2. Plug your device into your computer.
3. Open iTunes, click your device (in the sidebar or at the top-right if you have the sidebar disabled) and choose "Back Up Now." If the jailbreak process fails, you can restore to this backup and try again.
4. If your device is locked with a passcode, you must temporarily disable it. Open the Settings app, navigate to General and then Passcode Lock. Enter your passcode, then tap "Turn Passcode Off."
5. Your iTunes backup password must also be disabled. In iTunes, click your device and then untick "Encrypt Local Backup." Enter your password, then allow iTunes to backup your device again. If this option is greyed out: On the device, open Settings, tap General, tap Profiles and remove all entries there.
6. Download evasi0n by clicking the blue button for your operating system.
7. Close iTunes, then open the evasi0n app. For best results, ensure your device is showing the home screen and no other apps are open.
8. Click Jailbreak. This process will take a while, so give it a few minutes and try not to do anything that could interfere.
9. You'll be asked to open the Jailbreak app that appears on your home screen. It may be on the second page. Tap it to continue the jailbreak process.
10. After the jailbreak completes, Cydia will appear on your home screen. Open it and wait for it to download the latest package data from its repositories - you'll know it's done after "Reloading Data" shows up for a few seconds and disappears.
11. You can now install anything you want. Don't forget to enable device and backup passwords if you disabled them.

If evasi0n doesn't seem to recognize your device:

Make sure you have the latest version of iTunes installed, and make sure you're using a USB port that works. People on Windows may need to run evasi0n as an administrator. If that doesn't help, try restoring your device with iTunes and then seeing if evasi0n recognizes it.

If you have a passcode required because of Exchange:

Try removing the Exchange server profile on your device. Then you should be able to disable the passcode (and the encrypted backup option if necessary) and jailbreak your device. After jailbreaking, you can put the Exchange profile back.

How to jailbreak iOS 6.1.3 tethered on older devices

This tethered jailbreak for 6.1.3 is only available for iPhone 3GS, iPhone 4, and iPod touch 4th generation (which have low-level bootrom exploits available that permit tethered jailbreaking on any iOS version). There is no jailbreak available for iOS 6.1.3 or 6.1.4 for newer devices, and the major jailbreak developers intend to wait for iOS 7 before trying to build a new jailbreak.

To jailbreak your iPhone 3GS, iPhone 4, or iPod touch 4th generation:

1. Download the IPSW (firmware file) for your device for iOS 6.0 (here's a convenient list of download links).
2. Open the latest version of redsn0w (redsn0w 0.9.15b3), click "Extras", click "Select IPSW", choose the iOS 6.0 IPSW you downloaded, and then click "Back" at the bottom of redsn0w.
3. Click "Jailbreak".
4. Make sure Cydia is selected.
5. Follow the instructions to put your device into DFU mode.
6. Wait for the jailbreak to finish.

To boot tethered (necessary after a device with a tethered jailbreak is rebooted and right after it is jailbroken):

1. Make sure you have the IPSW (firmware file) for your device for iOS 6.0 (here's a convenient list of download links).
2. Open redsn0w 0.9.15b3, click "Extras", click "Select IPSW", and choose the iOS 6.0 IPSW you downloaded.
3. Click "Just Boot".
4. Follow the instructions to put your device into DFU mode.
5. Wait for your device to boot up jailbroken.
