Hello everyone. As you may know, the latest untethered jailbreak for iOS 5.1.1 has been released. In my last tutorial, I explained how to jailbreak your device on iOS 5.1.1. If you don't have official SIM for your iPhone, you will not be able to activate it after restoring. So now in this tutorial, I will explain how to Jailbreak, Activate and Unlock your iPhone on iOS 5.1.1.
Please note that I have used some old screen shots to save bandwidth. It does not affect the process at all.
This tutorial is not for iPhone 4S as iPhone 4S is not yet supported.
Step 1
Downloading everything.
Download iOS 5.1.1 IPSW for your iPhone. Be careful while downloading and download IPSW only for your device. Click here to download IPSW.
Download sn0wbreeze 2.9.5 or greater. Click here.
Step 2
Creating custom IPSW.
Step 2.1
Run sn0wbreeze.
Click OK. Click Next.
Step 2.2
Click Browse for an IPSW and browse to the IPSW you downloaded. Your IPSW will be verified and sn0wbreeze will show you the version. Make sure it is correct. If you have iPhone 3GS, it will ask if it is old or new bootrom. Select appropriate option. Click Next.
Step 2.3
Select Expert Mode.
Step 2.4
Now click General and click Next button.
Step 2.5
Click the Activate iPhone (hactivate) option. Leave everything as it is and click Next, Next and Next.
Now click Build IPSW and click Next.
Now sn0wbreeze will start creating a custom IPSW. Wait for the process to finish.
Step 3
Entering Pwned DFU mode.
Once sn0wbreeze finishes the process, it will ask you if you want to enter Pwned DFU mode. Click yes. Now sn0wbreeze will guide you to enter Pwned DFU mode, so you can restore using the custom IPSW. Click Start and follow the steps shown. After successfully entering Pwned DFU mode, you can close sn0wbreeze.
Step 4
Restoring using custom IPSW.
Open iTunes. Hold Shift button and click Restore. Release Shift key. Browse to Desktop and select the IPSW you just created using sn0wbreeze.
Now iTunes will start restoring your device. After restore is complete, your iPhone is already Jailbroken and Activated.
After the restore process is finished, you can proceed to the next step to unlock your iPhone. So first finish the steps displayed on your iPhone and get to the home screen.
Step 5
Unlocking your iPhone.
There are three method of unlocking your iPhone. First is software unlock - ultrasn0w and second is hardware unlock using Gevey SIM or R-SIM. The third one is with saved SAM unlock tickets.
Step 5 A
Unlocking using ultrasn0w.
Note : ultrasn0w can unlock particular iPhone models and basebands. So if your iPhone meets the following requirements, you can use ultrasn0w to unlock it.
ultrasn0w requirements - iPhone 3G, iPhone 3GS, or iPhone 4 with baseband - 01.59.00 (in iPhone 4) 04.26.08, 05.11.07, 05.12.01 or 05.13.04 (in iPhone 3G and 3GS). If you used iPad basbeand 06.15.00 on your iPhone 3GS, you can unlock too.
Configure Wi fi on your iPhone if not already done.
Now open Cydia and search for ultrasn0w and install it.
Reboot your iphone and you are done.
Step 5 B
Unlocking using Gevey or R-SIM.
Follow steps as described by the SIM interposer manufacturer. It is also possible that it may not support iOS 5.1.1 yet.
Step 5 C
Unlocking using saved SAM Unlock tickets.
If you unlocked using the SAM unlock method, and have backed up the Lockdown folder, you can now use it to unlock your iPhone.
Open Cydia and install SAM.
Now open SAM and click Revert Lockdown to stock.
Close SAM and connect your iPhone to your computer.
Use an iPhone browser like DiskAid and browse to the /var/root/Library and delete the Lockdown folder there.
Now copy the Lockdown folder you backed up to /var/root/Library. If you used redsn0w to backup Lockdown, you will have the folder in .zip format so unzip it and then copy the Lockdown folder to /var/root/Library/ on your iPhone.
Reboot your iPhone. Open SAM and disable it.
Reboot your iPhone again and you should see signal bar soon.
That's all.
