SAM is a jailbreak app for Cydia that allows you to unlock your iPhone so that you can activate and use a non-stock SIM card that is not supported by your existing carrier. SAM (Subscriber Artificial Module) can be easily installed and applied to any jailbroken iPhone that has Cydia installed. The developer of SAM, Sam Bingner (@sbingner), has made the process of installing SAM a lot easier with the latest version. This is good news for those who are new to unlocking. Previously you would have had to connect your iPhone to iTunes, and use the original SIM card and get a hold of country/carrier and SIM IDs to perform an unlock. With the latest version of SAM (version 0.1.16.-1), unlocking is now a streamlined process that involves just a few taps and a few minutes of your time.
The unlocking procedure using SAM currently works on most iPhones, including the iPhone 4S, which is great news. This means you can just take out your ATT sim card and use a T-Mobile SIM on your iPhone, for example. Unlocking an iPhone is great for those who want to use a different carrier than the one their iPhone is “locked” into at the moment. Reasons for wanting to use a non-standard carrier vary from user to user, but it can be good for those traveling abroad, and also to use a non-standard phone and data plan on an iPhone which could help some people save money etc.
Update: As reported by a few users already, Apple has “patched” their activation servers so that the SAM unlock may not work for new users any longer. If you did have an activation ticket from before, you can still use SAM. We will keep you posted if new unlocking methods are uncovered.
Warning: A quick word of caution. Please proceed with unlocking at your own risk!
The following are the detailed steps on how to download and install SAM on a jailbroken iPhone.
