Unlock an iPhone 4S with SAM in Just 12 Easy Steps

Hacker Loktar_Sun just discovered how to easily unlock an iPhone–including the iPhone 4S, which will free you from your carrier’s tyranny. All you need to complete the step-by-step unlock tutorial, is a jailbroken iPhone that can be activated in iTunes (and that is, not officially blacklisted).

The following process requires a computer with the latest iTunes installed and working internet connection:

  1. Go to Cydia, add repo.bingner.com as an app repository, and then search and install Sam Bingner’s Subscriber Artificial Module (SAM) package.
  2. Launch SAM by tapping the SAMPrefs icon.
  3. Go to utilities and select “De-Activate iPhone”, your ActivationState under “More Information” should now be “Unactivated”
  4. With SAM enabled, choose “By Country and Carrier” in “Method”; find your carrier, for some carriers operating more than one Carrier ID you may need to select “SIM ID”; easy to tell since iTunes will not activate if the wrong IMSI is selected.

  5. Go to “More Information,” copy the International Mobile Subscriber Identity (IMSI) in SAM Details, and then tap “Spoof Real SIM to SAM.”
  6. Go back to the main SAM screen and change your “Method” to manual. Paste or enter the IMSI string we saved in Step 5.
  7. Connect your iPhone to your computer and allow iTunes to do its job (namely re-activating 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 1.

  8. Double click the “Phone Number” parameter in iTunes to check and ensure the ICCID matches the SIM card. Repeat from Step 1 and onward if it does not match.
  9. Disconnect from the computer, and then quit iTunes when the reactivation process is finished.
  10. Disable SAM in the SAMPrefs app. Ignore the source article that instructs to uninstall SAM and delete the lockdownd folders.
  11. Connect the iPhone to the computer again. iTunes will appear and claim it cannot activate the iPhone.
  12. Close iTunes, and then open again. Upon launching, iTunes will activate the iPhone. The result–one unlocked iPhone!

  13. That’s it.!


  • Your iPhone will now “only work” with the SIM card employed during the aforementioned steps. Because, the iTunes was made to believe that SIM’s ICCID is one of the intended carrier.

    The phone can be rebooted without losing teh “unlock” atleast as of now, and can connected to iTunes.

  • If your push notifications stop working, go to SAM again and click on Clear Push then connect to iTunes again.
