iPhone Dev team has just released a new version of Redsn0w, which finally allows iPhone 4 GSM, iPhone 4 CDMA and iPhone 3GS 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 iPhone running iOS 5.0.1 using Redsn0w.
Here are some important points to note before you proceed.
- This iOS 5.0.1 Untethered Jailbreak guide is meant for iPhone 4 and iPhone 3GS users.
- Important note to iPhone unlockers: Please don’t use this guide directly if you want to preserve your iPhone’s baseband.
- Redsn0w 0.9.10b5c does not support iPhone 4S currently, but pod2G is working hard on it. We’ll keep you posted.
- Please do not forget to backup your iPhone before you proceed with iOS 5.0.1 Untethered Jailbreak.
- If you’ve jailbroken your iPhone 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 iPhone 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 iOS 5.0.1 Untethered Jailbreak process is complete, do not forget to checkout our article on tips to keep your iPhone secure.
- Please ensure you are running latest version of iTunes i.e. iTunes 10.5 or later.
Update: Please note that some readers are reporting issue with iBooks after jailbreaking their iPhone.

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