How to jailbreak iOS 6.1.6 untethered on iPhone 3GS and iPod touch 4th Generation using redsn0w (and the p0sixspwn untether package).

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 (Windows download | Mac download), 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. Close redsn0w.
   
7. Reopen redsn0w, click "Extras", click "Select IPSW", and again choose the iOS 6.0 IPSW you downloaded.
   
8. Click "Just Boot".
   
9. Follow the instructions to put your device into DFU mode.
   
10. Wait for your device to boot up jailbroken.
    
11. Install the "p0sixspwn" untether package from the Cydia/Telesphoreo repository (a default Cydia repository). (But if you have an old bootrom 3GS, you can skip this step.)
    

If redsn0w gets stuck in the reboot process, your antivirus software is silently interfering with it. This is a known issue. The only antivirus product known not to interfere with redsn0w is MSE (Microsoft Security Essentials / Windows Defender). Any others should be disabled, or, if that doesn't work, uninstalled.

How to jailbreak iOS 6.1.3-6.1.5 untethered on all devices (except Apple TV 3) using p0sixspwn (Mac and Windows).

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. Go to p0sixspwn.com and download the tool.
   

1. Click Jailbreak. This process will take a while, so give it a few minutes and try not to do anything that could interfere.
   
2. Follow the provided steps.
   
3. 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.
   
4. You can now install anything you want. Don't forget to enable device and backup passwords if you disabled them.
