If you had trouble unlocking your iPhone using SAM then we’ve some good news for you.

Sam Bingner – developer of Subscriber Artificial Module (SAM) has updated it to make it a lot easier to unlock your iPhone.

You no longer need to worry about having the original SIM or copy the IMSI. It just works. He tweeted few hours back:

The latest update for SAM should fix some issues with the activation if you click in SAM, and give you a pretty indicator while you wait.

Here’s the simple step-by-step instructions to unlock your iPhone using the updated SAM jailbreak tweak:

Step 1: Launch Cydia on your jailbroken iPhone.

Note: If you haven’t jailbroken your iPhone yet then check out our How to Jailbreak webpage for links to the latest tutorial to jailbreak your iPhone.

Step 2: Sam Bingner’s SAM (Subscriber Artificial Module) package

Note: If you’ve already installed SAM then install the latest version of SAM via the Changes tab and jump straight to Step 4.

  • Tap on the Manage tab
  • Then tap on Sources
  • Then the Edit button
  • Enter as the Cydia/Apt URL
  • Tap on Add Source

Cydia will verify the URL of the repo and successfully install it.

Step 3: After the package is installed, you need to Install SAM and SAMPrefs.

  • Either tap on Changes tab or use the Search tab to search for SAM
    • Select SAM for the list of search results
    • Tap on the Install button
    • Then tap on the Confirm button.
    • Tap on the Reload Springboard button when prompted.
  • This will also install SAMPrefs

Step 4: Insert the SIM card that you want to use in your locked iPhone.
