iPhone Dev team has released a new version of Redsn0w using pod2G’s untethered jailbreak, which finally allows iPod touch 4G and iPod touch 3G users to perform an untethered jailbreak.

In this guide, we will take you through the step by step procedure to perform an untethered jailbreak on your iPod your iPod touch running iOS 5.0.1 using Redsn0w.

Here are some important points to note before you proceed.

• This guide is meant for iPod touch 4G and iPod touch 3G users. iPhone users can checkout this guide and iPad users can checkout this guide.
• If you’ve performed a tethered jailbreak on your iPod touch running iOS 5.0.1 then checkout this guide to convert it to an untethered iOS 5.0.1 jailbreak.
• Please note that jailbreaking your iPod touch may void your warranty and hence proceed with caution and at your own risk.
• Please do not forget to backup your iPod touch before you proceed. You can refer to this post for instructions on how to backup your iPod touch.
• If you’ve jailbroken your iPod touch then you can use jailbreak apps such as AptBackup, PkgBackup or xBackup from Cydia to take a backup of all the jailbreak apps and tweaks so you can reinstall them easily after successfully jailbreaking your iPod touch rather then installing them individually. However, if you’re moving from iOS 4.x to iOS 5, it may be a good idea to reinstall the jailbreak apps to avoid compatibility issues.
• After the jailbreaking process is complete, do not forget to checkout our article on tips to keep your iPod touch secure.
• Please ensure you are running latest version of iTunes i.e. iTunes 10.5 or later.

Troubleshooting Tips:

Error 16xx:

If you’re getting error 16xx then it is most likely due to host file entries pointing to Saurik’s server. You can either remove the host file entries or try jailbreaking from another computer.

Error 3194:

You have probably not put the iPod touch in DFU mode properly. Try the step by step guide again.

Cydia Issues:

It looks like some of the repositories are getting hammered due to the surge in traffic, so keep trying or try after sometime.

• iPod touch 3G – iPod3,1_5.0.1_9A405_Restore.ipsw
• Click on Extras instead of Jailbreak
