In this guide you'll learn how to jailbreak iOS 5.1.1 on iPhone 3GS, iPhone 4 and the first-gen iPad on Windows with the help of latest redsn0w version. Note that this method currently works with devices mentioned above and doesn't support any of A5 devices, namely iPhone 4S and the new iPad as well as iPad 2. If you own any of those devices and updated to the latest iOS you can successfully downgrade to iOS 5.0.1 which supports untethered jailbreak. In case if your device fits this method but it's on iOS 5.1 - you can still us this guide to break from App Store jail because the exploits for iOS 5.1 and 5.1.1 are pretty much the same.

How To Perform iOS 5.1.1 Jailbreak on iPhone 3GS, iPhone 4, iPad:

Things you will need to do this:

• redsn0w 0.9.11b4 for Windows (get it here)
• iOS 5.1 (yes, not the 5.1.1) - direct links iPhone 3GS, iPhone 4, iPad
• iDetector to check your iPhone 3GS bootrom version (link)
• Saved SHSH blobs use TinyUmbrella or iSHSHit to do that.

Step One: First things first. Backup your device via iTunes as usual. Step Two: Upgrade to iOS 5.1.1. Skip this step if you are already running this firmware. Step Three: Run redsn0w. It's better to run as administrator to avoid issues during the process. To do that simply right click on the program's icon and select 'Run as administrator'. Step Four: Click Extras and then Select IPSW. Step Five: Browse for earlier downloaded iOS 5.1 iPSW file for your gadget. Step Six: Select your bootrom version if you're jailbreaking iPhone 3GS. Step Seven: Wait until redsn0w creates custom firmware. Step Eight: In the next window select only Install Cydia from the list of options. You don't need anything else. Step Nine: Put your device into DFU mode. Check here how to do that. Step Ten: Redsn0w will detect your device and exploit it with limera1n. Step Eleven: After device reboots you'll see a white Cydia icon on your SpringBoard. That will mean the process is almost at the end. Step Twelve: Return to redsn0w, go to Extras and choose Just boot options. Step Thirteen: Go to DFU mode again and wait until everything's done. Step Fourteen: iDevice will now boot in tethered mode with working Cydia app. To avoid the need to boot tethered every time your device is rebooted or powered down - install SemiTether Cydia tweak from BigBoss repo.
