iPhone Unlock any iPhone 3G, 3GS, 4, 4S on any Baseband with SAM new method

What the heck!

So I go out and purchase a new 3G S MC640LL/A and get a new phone number for it on a new account with AT&T. It's got 5.1 and 5.16.05 on it. I tether jailbreak it with redsnow 0.9.10b8b. Launch Cydia. I didn't install anything. I put my T-mobile SIM in it just for kicks and it just works after two minutes of searching! I can call out and receive!

I think Apple has much bigger problems right now than this whole SAM thing.

It's persistent after a reboot as well.

Damn so I restore, leave the T-Mobile SIM and it is still recognized. Of course I need an AT&T SIM to activate it. Wow I'm actually @#%# this phone is unlocked. Back to the store it goes.

Backup your activation ticket - that ticket might be completely unlocked.

Edit: Wait, why are you mad that it's unlocked? I can't think of any real disadvantage...
 
The iPhone 4 that I have is from a friend that used it on AT&T...the SAM method is asking for a SIM ID. Where would I get that?
 
The new redsn0w has the option to Backup Activation Tickets.

There's an option to backup activation with SAM, but I don't think it's the same function as it disappears once the new SIM is activated.

It looks like the new SAM method only requires iTunes the first time: Deactivate iPhone, copy IMSI from AT&T SIM, insert new SIM, Spoof Real SIM to SAM, paste IMSI in main SAM IMSI field, and connect to iTunes. Then disable SAM option, deactivate iPhone, and click Attempt Activation under Utilities. I swear I got it to work without iTunes one time, but that may have been using a SIM that was already activated. It does take a few tries sometimes.

If you reboot with the tethered jailbreak(5.1), your new SIM will still have service, which is nice if you don't need the jailbreak all the time.

So I have a prepaid SIM Card from Germany that I plan to use next month. I am currently on AT&T, iphone 4s. After going through the process of unlocking the phone for the prepaid SIM Card, can I just pop the AT&T SIM CArd back in and the phone is ready to go again on the AT&T network?

use the latest version of redsn0w for that, youtube/google for assistance
I don't understand why some believe Gevey is better than this? this is free and it won't eat up your battery life like GEVEY as it will work normally.
 
After the phone is unlocked to my SIM using this method, can I now restore (to remove the tethered jailbreak) and then add back the Lockdown folder items, and still have an unlocked iPhone??

No, phone must remain jailbroken to access file system.

I actually did this on two phones.. I ran the SAM unlock and then restored them back via a normal iTunes restore. Upon restoring the phone's backup to it, signal picked up and has not disappeared upon SIM removal, reboot, or anything. The unlock stays for that SIM if you keep it in there and do a restore.

What software version were u on? And what did u restore to? I'm assuming that u were on 5.1, tether jb and restore back to 5.1?

That makes sense if you restore to backup.
But I was thinking more in terms of manually restoring the files using SB or SSH

Good to know that restoring to backup works, thanks for sharing !

@romeo0119, one of the phones was 5.1 tethered, unlocked and then restored to stock. The other phone was 5.0.1 untethered, restored and then rejailbroken just for test purposes.

@dhlizard, Yup haha! Only works with a restore to backup.. but yeah I get what you mean. You're welcome! I think it was mentioned earlier too but more confirmation can't hurt :]
 
So let me get this straight, tether jb, run Sam to get phone unlock, back up phone. Back up w iTunes, restore to factory, then restore from the back up?
 
One question... Let's say I use this to unlock From X to Y.
If I do that, the unlock will work for all sims from Y company, or just for the one I've used?

SAM only works once per sim card. So, if you take out one Y card, then put in another Y, you need to unlock again.
 
I have a iPhone 4 iOS 5.0.1 bb 4.11.08 locked to Swisscom. I used Sam to unlock the phone it worked great then I did a restore from iTunes to stock iOS 5.1 bb 4.12.xx and then guess what happened. That's right you guessed it. It remained unlocked. awesome unlock.
