Unlocking an iPhone 4S or iPhone 4 is easier now, thanks to the Subscriber Artificial Module (SAM) package unlock that was revealed this weekend.
Now there is a reliable method for making this work every time.
The good news is that this procedure will likely become even easier as time goes on, and needless steps will get eliminated. Now it is possible to switch back and forth between our AT&T Subscriber Identity Module (SIM) card and our T-Mobile SIM card without having to reconfigure anything. This is awesome.
Following video shows the procedure of unlocking any iPhone on iOS 5 or higher (running any baseband) using the SAM jailbreak package:
Now we explain the procedure with all steps:
STEP 1 – Start with adding the following repo to your Cydia sources: repo.bingner.com and then install SAM.
STEP 2 – Open SAM. Go to Utilities, and tap Deactivate.
STEP 3 – Return to the SAM main menu, and tap More Information. Under SIM Details copy your International Mobile Subscriber Identity (IMSI) number.
STEP 4 – Remove your SIM. Replace it with the SIM you wish to use (i.e. T-Mobile).
STEP 5 – With SAM enabled, tap Method, and select By Country and Carrier. Go back a menu, and select the correct country and then the correct carrier for your SIM card.
STEP 6 – Go back to More Information. Tap Spoof Real SIM to SAM. Next under SAM Details, delete the current IMSI number, and replace it with the one you copied in STEP 3.
STEP 7 – On the SAM main menu go to Utilities, and tap Attempt Activation. Your device should respring if done correctly.
STEP 8 – Open SAM and disable SAM. Close SAM.
STEP 9 – Open iTunes and plug in your device to your computer. You may have to unplug it and plug it in a few times. You have to be patient. You should receive a message stating that it failed to activate your device. Click OK. Be patient, and eventually you will see the carrier logo for your new SIM.
Saving Activation Ticket to Preserve Your Unlock:
Hacker MuscleNerd has stated that he recommends saving off your Activation Ticket for each SIM that you use, as they might come in handy in the future. These can be found at: /var/Root/ibrary/Lockdown and you can access this easily with iFile or via SSH.
This is perfect for those who travel abroad or who need a second SIM Card.
