These are instructions on how to restore your iPhone unlock ticket obtained using the SAM unlock method.
If you've unlocked with SAM but haven't backed up your unlock ticket, you should do so immediately by following this tutorial. To follow these instructions you will need to have the unlock ticket and iFile installed. You can get iFile from Cydia.
Step One Insert your previously unlocked SIM card and make sure SAM is disabled in SAMPrefs.
Step Two Email yourself the zip archive created when you backed up your unlock ticket. Open the email on your iPhone and tap to open the attachment. When prompted to select an application to open the attachment with choose iFile.
Step Three When iFile opens it will ask you to choose between Zip Viewer and Unarchiver. Choose Unarchiver and tap the Done button when it's completed extracting.
Step Four Tap the Edit button at the top right of the screen and select the Lockdown folder that was just extracted.
Step Five Press the Clipboard button at the bottom right and choose Copy/Link from the popup menu. Then press the Done button at the top right of the screen.
Step Six Use the back button at the top left of the screen to navigate to the /var/root/Library folder. Press the Edit button at the top right of the screen and select the Lockdown folder.
Step Seven Tap the Trash icon at the bottom of the screen and choose Move File to Trash from the menu that appears.
Step Eight Tap the Clipboard icon at the bottom right of the screen and choose Paste from the menu that appears.
Step Nine Press the Done button at the top right of the screen then reboot your device.
Step Ten Once your iPhone has been restarted it will pick up the network for the unlocked SIM card.

I need help with the following:
iphone 4 (hacktivated): backed up, restored to a hacktivated Sn0wbreeze 5.0.1 , injected backed up tickets using SAMprefs, using your method, then revert lockdownd to stock. everything works perfect (push and everyth) except HUGE BATTERY DRAIN (10 hours battery maxxx) and HEAT on the upper right corner.
I m 100% sure it has something to do with certs, just don't know how to fix it.
thanks for the help
Hi, I think I've solved the problem. I just recently updated and untethered iOS 5.1.1 today. I had the same problem as you cause my carrier didn't show after i restored the unlock ticket using this method. But since you restored the ticket with this method, try this. If you have SAM installed on your iPhone, keep it disabled. Go to utilities and tap 'Revert Lockdownd to Stock'. Your carrier should be appear after. Mines did, so maybe your can too.
