But as always, there is no magic spell in the world to stop jailbreak. iPhone Dev Team has released newer version of RedSn0w to bring almost all iOS devices running 5.1.1 jailbroken tethered.
All users of iPhone 4, iPad 1, iPod touch 4G, iPod Touch 3G should now be happy that all security patches included within the new firmware still not being capable to patch the tethered jailbreak exploit. As always, it requires a lower firmware version. And if you want to do so, simply read following steps to put your iDevice jailbroken.
1- a. Download RedSn0w v0.9.10B8B:
b. Once downloaded, extract the .zip file using Winzip, Winrar or 7zip
c. Always make sure you backup your iPhone first.
2- Download iOS 5.1 .ipsw file (not iOS 5.1.1)
3- Now launch RedSn0w up
4- Click on “Extras” >> choose the “Select IPSW” button
5- Now locate the iOS 5.1 .ipsw file
6- Now click on “Jailbreak” to start the process (But make sure you have Cydia ticked for install)
7- Read and follow on-screen instruction to put your device into DFU mode
8- Sit tight and wait for Redsn0w to do its job.
Don’t get panic if you seen some texts scrolling down on your iPhone’s screen
