Note: You will need to perform this for each SIM card that you use to unlock. So for instance, if you have an Orange SIM card, pop out your T-Mobile SIM, and perform the exact same steps while connected to the Orange network.
Step 1: Download iFile from Cydia
Step 2: Open iFile and navigate to /var/root/Library/
Step 3: Tap edit in the upper right-hand corner, and tap the circle next to the Lockdown folder.
Step 4: Tap the Zip button at the bottom of the screen (second from the left), and name your file something that you can recognize. For instance, if you’re currently on your T-Mobile sim, name it Lockdown-Tmobile.
Step 5: Once your zip file is created, scroll down to the bottom of the page to find it. Tap the circle next to your zip file, and tap the mail button. This will allow you to email the zip file as an attachment to save for future use.
That’s all there is to it. Your activation ticket is now safe and sound for future use if needed.
