The iPhone Dev-Team has done it again! In less than 24 hours after the release of iOS 5.1, a Jailbreak has been released! RedSn0w, a Jailbreak tool, has been updated allowing those using the latest iOS 5.1 to set their devices free! It works for all A4 devices including the iPhone, iPad and iPod touch devices except, of course, the iPhone 4S and the iPad 2. As you may have guessed it by now, it is TETHERED, meaning you will need to connect your device to a computer to boot tethered each time it is switched off for whatever reason. The ‘SemiTether’ patch eases the tethered scenario by allowing devices to boot without connecting to a PC or Mac, although features are extremely limited, thus it will have to be booted tethered in order to function at optimum level once more.

NOTE:

• As already mentioned, this jailbreak does not work on the iPad 2 or iPhone 4S.
• If you unlock with GEVEY or Ultrasn0w, DO NOT update to the stock iOS 5.1 firmware. Skip to the latter part of this guide for more info.
• You will be booting tethered quite a bit, so if you don’t think you can deal with constantly connecting and rebooting, wait for an untethered or downgrade to iOS 5.0.1/4.x.

(Watch the video for illustration guide)

Step 1: Connect iDevice via USB to your computer

Step 2: Launch Redsn0w
If you are running redsn0w on Windows, you will need to do the following steps before launching the redsn0w:

• Right click on redsn0w.exe and select Properties
• Click Compatibility tab and check the “Run this program in compatibility mode for” option and select Windows XP (Service Pack 3) from the dropdown menu.
  
• Click OK. Now you can launch redsn0w by double-clicking on redsn0w.exe

Step 3: Click Jailbreak

Step 4: Set your iDevice in DFU mode:

• Turn OFF iDevice
• Hold POWER button for 3 seconds
  
• Simultaneously hold POWER and HOME button for 10 seconds
  
• Let go of the POWER butto while still holding HOME button for 15 seconds
  

Step 5: Once you’ve successfully entered DFU mode, RedSn0w will identify your firmware aka IPSW along with options, like: Install Cydia, Install custom bundle, Enable multitask gestures, Deactivate.

Step 6: You just need to select “Install Cydia” option then click Next and let the process run.

Step 7: Now you will see your iDevice preparing the Jailbreak data!

WARNING: Cydia will not work unless the following steps are done.

Step 8: Click back on RedSn0w and select “Extras” then on “Just Boot”.

This will perform a tethered boot, and once your device returns to its Home screen, you will see a usable Cydia app icon.

Step 9: Set iDevice to DFU mode as we did earlier, and let it run again.

Step 10: Once iDevice is booted back up, Cydia should be working.

Open Cydia, and enjoy your iOS 5.1 jailbreak!

 

Booting Semi-Tethered (Optional)

The “SemiTether” patch may work through to 5.1. It’s a cross between tethered and untethered – allowing you to boot your device without a computer, but the available features are somewhat limited, so you’ll need to boot tethered through Redsn0w in order to enjoy a fully-functional break.

It’s free, and available over at the BigBoss repo: http://thebigboss.org/semitether.

Note To Unlockers:

If you use the GEVEY SIM interposer or Ultrasn0w to unlock your iPhone, you will need to create a custom .iPSW, in order to preserve your baseband. In Redsn0w, select “Extras”, then “Custom IPSW”, locate your iOS 5.1 file, and let Redsn0w work its magic. Then enter pwned DFU mode (Extras > Pwned DFU) and restore to your custom firmware via iTunes. After that, you’ll be able to unlock with GEVEY or Ultrasn0w (when it is available).
