iPhone 4 5.1.1 (9B206) Firm 04.12.01

Hi Wiktor222, I have found that still many have the same kind of jailbreak issue with iPhone and Absinthe, but it has worked for many others also. Regarding iTunes, i have found it to be an important step to be followed. Below are the steps to jailbreak just in case you missed any one of them.

Step 1: Download Absinthe 2.0 for Windows from our dedicated downloads page.

Step 2: Extract, and right click on the absinthe-win-2.0.exe icon and select Run as Administrator. This first file is a self extracting zip file. Once you do this, a new folder will be created on your desktop called absinthe-win-2.0 with the necessary files.

Step 3: Open the absinthe-win-2.0 and right click on the absinthe.exe icon and select Run as Administrator.

Step 4: Connect your eligible iOS 5.1.1 device, and verify that Absinthe recognizes the correct name of your device.

Step 5: Click the jailbreak button on Absinthe, and let it run. You should see a progress bar.

Step 6: Eventually your device will appear as if it’s performing a restore, this is normal.

Step 7: Once the device has completed the “restore”, you should notice the Cydia icon on your Home screen.

Step 8: Once Absinthe reports that the process is complete, you can close Absinthe and disconnect your device.

Step 9: Open Cydia and let it configure itself for the first time. Congratulations, your iOS 5.1.1 device is now jailbroken untethered!


Warning***: Before you continue make sure to do a backup of your device in iTunes as you may lose your Camera Roll during this process.

 

Works also for me!
