Jailbreak CDMA iPhone 4S iOS 5.1.1
Now on to jailbreaking. First, we're going to download the latest version of the Absnithe Jailbreak tool. Find the version for your operating system and of course make sure to download from a reliable source. I recommend you save the download to your desktop or another folder that's easy for you to find. After your download is finished, extract or unzip the Absinthe file and launch it. You may get an operating system warning, then move on.
Absinthe may not detect your iPhone, so unplug your iPhone from your computer and then plug it back in. iTunes may launch, but just close it. Now click on jailbreak and let Absinthe go to work. Durning this time, you iPhone will restart a few times. When the jailbreak process has finish, Absinthe will show you this message. Now let's finish the jailbreak process on your iPhone.
Note that sometimes after the jailbreak process, some icons on your iPhone will appear differently or turn completely white. We don't know why this happens, and it doesn't always happen, but your apps will still function properly even if the icons change.
Open the Cydia app on your iPhone and wait for the Cydia to prepare filesystem. After it's finished, you might see a message to unlock your SIM card, but you can do that later. Open Cydia again select your user type. I suggest you select User here. Now click done. Cydia will begin downloading and installing packages. You must let this process finish before going on to the next step or you will receive errors.
