How To Unlock Any iPhone 4S, 4, 3GS, or iPhone 3G To Use On Any Carrier With SAM
Lots of people would enjoy the freedoms of being able to travel across the world, and still easily be able to use their cellular phone. Trouble is, when purchasing a phone on a subsidized plan in the United States, carriers frequently have the device you purchased locked down to using only their network. Obviously this restricts the capabilities of the device in a way we don’t want restricted, and thus, the need to unlock phones has never been more desired.
We might be a little late to the game, but we’ve got everything you need to know about the new iPhone unlocking tool named SAM (Subscriber Artificial Module). With the collaboration of developer Sam Bingner, Loktar_Sun, and the Dev-Team, you can now unlock your iPhone 4S, iPhone 4, iPhone 3GS, and iPhone 3G to any carrier.
Before you begin your journey into unlocking your phone, there are a couple of things you should know:
- Your iPhone must be jailbroken. (Visit the Jailbreak tab above in the menu bar if you need help jailbreaking your phone)
- You don’t necessarily need to be on iOS 5, but it is recommended
- This will work on any baseband
- This will only work with the SIM you want to use. If you plan on swapping SIM cards then you must redo the process each time you insert the new card
Now that we got that out-of-the-way, let’s get started.
- Open up Cydia
- Select Manage from the bottom menu
- Go to Sources
- Press the Edit button on the top right
- Press the Add button on the top left
- Enter http://repo.bingner.com and press Add Source
- Return to Cydia
- Select Bingner from the list of Sources
- Choose SAM from the list. (As of this tutorial, SAM is on version 0.1.16-1)
- Press Install on the top right corner
- Now press Confirm on the top right corner
- Press Reload Springboard
- Now insert the SIM card you want to use into your phone and select SAMPrefs. If you’re using a Gevey SIM or any other hardware unlocking method, make sure to remove it and insert only the tray and the SIM card inside the phone
- Make sure your Method is set to Auto Detect and tap Utilities. Note: Auto-Detect might not always work. If that’s your case, you can change Method to By Country and Carrier and select the phone’s original carrier manually. (Original carrier means the company the phone was originally locked to)
- Press the Attempt Activation button. If you don’t see Attempt Activation, you need to select De-Activate iPhone and the Attempt Activation button should appear after that
- A pop-up will appear “Please wait… this may take a while” It’s in your best interest to be patient and let the phone complete it’s task
- Once your phone reboots, you should see it acquiring a signal in which you will now be unlocked to. Tadaaaa!!
You are now fully unlocked to the SIM card you have inserted in your phone. You will be able to reboot your phone and still maintain your unlock. Before you go celebrating, make sure you back up your unlock ticket which we hope will serve us well in the future when new iOS updates come out.
The easiest way to back up your unlock ticket is to SSH into your phone (iFile, WinSCP, etc…) and going to the following directory:
You can save your Lockdown folder with the name of the SIM you used, just in case you want to unlock more SIM cards, you can have a back up of all of them. It is still unclear if the unlock will work after an update, but as always, it’s safer to stay away from any iOS updates until more information becomes available.
Ok, that’s it. I promise. You finally have an unlocked phone and a back up of your unlock ticket. Call your relatives and tell them all about it. Even if they won’t understand a word of what you just did.
