Yesterday Loktar Sun found a trick, while experimenting with SAM (subscriber artificial module), which allowed him to unlock iPhone running on iOS 5+. You can also backup the activation tickets of unlocked iPhone for future use. These activation tickets will be required to re-unlock your device after you restore a fresh iOS firmware on your device.
There are many methods and ways which we can use to save the activation directory from iPhone on our local machine. For example we can SSH into iPhone and download the required files using WinSCP. We can also use iFile from Cydia to zip the directory and mail it to inbox. Few hours ago MuscleNerd also released a new version of Redsn0w 0.9.10 b10 (a typo error, the latest version is b8 till now) to backup the iPhone’s unlock activation tickets directory.
Backing Up Unlock Activation Using Redsn0w:
Step 1: Download the latest version of Redsn0w. The download links are at the bottom of this post.
Step 2: Click on Extras and then on Even More.
Step 3: If the device is not connected with PC, you will see non-functional “Backup” button.
Step 4: Connect the device and hit “Backup” button. Leave the default directory if you want to save the back here and hit “OK”.
Step 5: You will see a message that the Backup has been created successfully. You can find the lockdown.zip file in the directory of Redsn0w. Or use the spotlight to search lockdown zip file.
You should use the same steps to save this backup every time you unlock your device having a different SIM card.

Can we just use an iPhone explorer program like iFunBox and go in and manually save the Lockdown folder? Because that is what I did. I hope that’s the same.
Yes, we can use any software.
I though we have to save the ticket only once. Thanks, now I’ll save the ticket for every new SIM.
