How Do U Jailbreak an Ipod 4 6.1.6

If you're an iPhone 3GS or iPod touch 4G user and have upgraded to iOS 6.1.6, which was released recently to fix a critical SSL bug then the good news is that it is still possible to perform an untethered jailbreak on your iOS device using a combination of Redsn0w and p0sixspwn.

In this article we show you how to jailbreak iOS 6.1.6 first using Redsn0w, and then converting it into an untethered jailbreak using p0sixspwn Cydia package.

Update (June 17): Please note a new version of p0sixspwn has been released which adds support for iOS 6.1.1, so you can use p0sixspwn directly to perform the untethered jailbreak on your device running iOS 6.1.6, instead of using this workaround.

Step 21: Wait for the process to complete, once it is complete, you should see the Lock screen on your iOS device.

Your iPhone or iPod touch has now been successfully jailbroken and you should see Cydia on the Home screen. If you don't find it on the Home screen, please don't panic, search for it using Spotlight. The jailbreak is currently a "tethered" jailbreak,

Convert Tethered Jailbreak to Untethered Jailbreak using P0sixspwn:

Step 25: Tap on Return to Cydia when prompted.

That's it, your iOS device has now been successfully (untethered) jailbroken.

Troubleshooting Tips:

1. Can't find Cydia:

If you can't find Cydia on the home screen then double check you have tethered boot your device. Please ensure you've followed steps 14 to 21.

2. Unsupported IPSW:

If you get an error message informing you that the IPSW is not supported by this version of Redsn0w, then it means you've downloaded iOS 6.1.3 firmware file in step 2 instead of iOS 6.0 firmware file. Please download iOS 6.0 firmware file to jailbreak your iOS device running on iOS 6.1.3.

3. Cydia closes immediately:

If Cydia closes immediately when you try to launch it, it means that you haven't installed p0sixspwn package from Cydia. Follow steps 22-24 mentioned above to solve this issue.
