Update: SAM has been updated, the instructions below have now been simplified. (I think.)

W/ new SAM you can unlock by putting in your original sim, click spoof under More Info, activate in iTunes, turn off SAM, activate again.


Anybody who does this unlock do NOT restore your phone until that is saved. I need to add code to save it properly. I'm going to sleep now



Whoops, didn't see the original thread: https://forums.macrumors.com/threads/1361745/


===========OLD METHOD===============

MuscleNerd and Sam Bingner have both confirmed this unlocked their iphone 4 s and iphone 4. Also confirmed working on the iphone 3 gs. Someone has confirmed after unlocking their iphone 4 that a restore with the new sim in it went fine and the iphone was activated again. An update to SAM will simplify these instructions:

How to: Unlock your iPhone with SAM
I thought the IMSI unlock saga is done and dusted but apparently there are more to it. All credit goes to Loktar_Sun from weiphone.com who pursued an earlier lead that many, yours truly included, have gave up as a viable exploit.

What do you need: A jailbroken iPhone that can be activated in iTunes (that is, not officially blacklisted), a computer with the latest iTunes installed and working internet connection. You will also need to know the carrier that your iPhone is locked to.

1. Step one: Install Sam Bingner's SAM (Subscriber Artificial Module) package. I recommend that you get it from repo.bingner.com since older versions have a different interface and may not work for this purpose.

2. Enter SAM by either going through the settings menu or find the SAMPrefs icon on your springboard. You will need to have the SIM card you intend to use in your phone.

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 or write down the IMSI in "SAM Details", 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. Unplug your phone, close iTunes.

9. Disable SAM. The source article says to uninstall SAM and delete your lockdownd folders; it's unnecessary.

10. Connect your phone to iTunes again, you should get an error saying that your phone cannot be activated. This is normal. Just close iTunes and open it again.

11. You should see signal bars in a short time, congratulations.

12. Push notifications may stop working after this procedure but can be easily restored with "clear push" utility in SAM followed by connecting to iTunes.

Your phone will work normally with your SIM card and that SIM card ONLY since we have tricked iTunes to think that ICCID is one of the intended carrier's. The phone can be rebooted and connected to iTunes freely without losing the "unlock", at least for now.

Since it does not involve emergency numbers or IMSI spoofing it will not have any of the issues associated with SIM interposers. Tested working on iOS 5.01 but should work with tethered 5.1 too.

Hi
Just asmall important note that im having trouble to figure out

do i must have the original sim?

cause most ppl who need unlock are ppl oversea that bought the phone in some other country and most likely wont have the original sim
 
My question is, is there a way to downgrade iPhone 3GS from 06.15.00 baseband? Being able to use SAM to unlock any firmware posts no importance to iPad firmware that blocks GPS signal

All sims are original, the difference is that some can unlock based on contract u have and other can't for you are free of contract

Check Musclenerd's twitter. He said no. You just need to know what carrier your phone was intended to work with.

this isn't as useful if i'm looking to unlock for resell value right? because it seems like it's sim chip specific?

Did you not read when you flash the baseband?
 
So I'm thinking, tether jailbreak the iPhone 4 that is on 5.1, go through all of this to unlock. But don't turn off the phone unless you can completely remove the jailbreak some how without doing a restore....

I think u can't rule it out, u don't know what tomorrow will bring about. Developers are thriving to facilitate many things

As the instructions indicated when you did this, everyone who installed the iPad baseband on an iPhone is stuck with that baseband. There is no way to change it. But if hoping that developers will someday provide a fix comforts you, dream on.
 
People at mmi have claimed they have gotten gsm sims to work in their sprint and verizon iphones even though they knew the phone was locked.
 
Quick question with the SAM unlock method....

Im on a sprint Iphone 4s.

Once I run and save the profile for the TMobile or ATT specific sim can I switch back and use the Sprint sim are am I going to have to reconnect to itunes to utilize sprint network again?
 
Did you not read when you flash the baseband?

Yes, I read it and that doesn't make it irreversible b4 we couldn't downgrade an iPhone but now u could as long as u have ur bolt saved
Comparatively, if u can flash an iPhone with iPad BB where shouldn't it be a way out -even in future- to flash iPhone with an iPhone BB

You need to look up the definitions of 'possible' and 'probable'.
