Step Eighteen
Tap Country and choose the country of your ORIGINAL SIM.



Step Nineteen
Tap Carrier and choose your ORIGINAL carrier that your iPhone is locked to.

Step Twenty Two
Tap Spoof Real SIM to SAM



Step Twenty Three
Go back to the main SAM screen and paste the IMSI number in your clipboard.



Step Twenty Four
Connect your iPhone to the computer and let iTunes reactivate your phone.



"Double click "Phone Number" parameter at the main device screen and make sure that the ICCID matches that of your SIM card." If not you need to start over from Step Fourteen."


Step Twenty Five
Unplug your iPhone from the computer and close iTunes.


Step Twenty Six
Reopen SAMPrefs from your SpringBoard and disable it using the Enabled switch.



Step Twenty Seven
Connect your iPhone to the computer and launch iTunes again. 



You should get an error saying that your phone cannot be activated. This is normal. Just close iTunes and open it again.



Step Twenty Eight
In a short time you should see signal bars. Congratulations!



Step Twenty Nine
You should now backup your iPhone unlock ticket in case this method is ever blocked. You can find instructions on how to backup the unlock ticket here.




IMPORTANT:
If push notifications stop after this process, you can restore then with the Clear Push utility in SAM, followed by connecting to iTunes.


Your phone will work normally with your SIM card and that SIM card ONLY since we have tricked iTunes to think that ICCID is one of the intended carrier's. The phone can be rebooted and connected to iTunes freely without losing the "unlock", at least for now.
