For those, who still have not upgraded their iDevice to the latest version, its time to move on guys. You can read the whole procedure from here below :-
Step 4: Extract the download redsn0w .rar file to your desktop and run the .exe file to launch Redsn0w 0.9.10b8b
Step 6: After opening the executable file, just Select the ‘Extras’ Tab and then choose the ‘Select IPSW’ option.
Step 7: When prompted, point to IPSW file from Step 4 (which is iOS 5.1) and select it.
Step 8: On the main home screen of Redsn0w, select ‘Jailbreak’ and then make sure the ‘Install Cydia’ option is selected before proceeding.
Step 9: The on-screen prompts will now walk you through the process to put the device into DFU mode. This is a requirement for the jailbreak process to be successful. Make sure to follow all steps carefully.
Step 10: When DFU mode is detected, Redsn0w will automate the rest of the process on-screen before finishing off on the device. During the process, it is entirely normal to see white lines of text scrolling down the device’s screen. When the device reboots, the jailbreak process is complete which should be evident by the presence of the Cydia icon on the home screen.
Since this is a tethered jailbreak, you will have to boot your device into tethered boot mode on every restart. You can do this by launching Redsn0w, select “Extras”, then”Just Boot” in order to boot your device tethered.
