Today, the Chinese hacker Loktar_Sun has shared a new method of unlocking absolutely any iPhone (the version of the modem is absolutely unimportant). Thus, this day became a turning point for the owners of "bricks" from Apple.
Leading hacker MuscleNerd from the DevTeam also confirmed the workability of this method by unlocking an iPhone 4S. It is possible that soon Apple will close this loophole, so we recommend that you save the activation file for your iPhone.

How to unlock iPhone 4 / 4S and iPhone 3GS using SAM.
Requirements for unlock.
1. Locked to the operator iPhone 4S, iPhone 4 or iPhone 3GS
2. Modem version 04.11.08, 02.10.04, 04.10.01, 04.12.01, 1.0.13, 1.0.14 and 1.0.11.
3. Firmware version iOS 5.0 and higher.
3. Installed iPhone jailbreak.
IPhone unlock process:
1. Add the repository to Cydia repo.bingner.com and install the SAM package from it; 
2. Insert into Sim phone the card that you want to use in the future (for example, MTS) and run SAM; 
3. In the main menu, go to the section utilities and click on "De-Activate iPhone"... After that, return to the main SAM menu and go to the section "More Information", you should see “Unactivated” in the ActivationState field, congratulations while everything goes well!) 
4. In the main SAM menu, go to the “Method” section and select “By Country and Carrier”. At this step, you need to know the country and operator that your phone is locked to. Let's look at an example from AT&T. In the Country field, select United states, and in the Carrier field, select AT&T (Cingular version). Finally, select "SIM ID" ( recommend the one that ends in 170).
Important! Very often, after the unlock process is completed and the device is connected to iTunes, an error occurs and iTunes writes that the inserted Sim card is not correct that means "SIM ID" did not fit. So you need to repeat the entire unlock procedure again and select another "SIM ID". 
5. Go back to the section "More Information" and copy or write down IMSI from "SAM Details"... After all this, click “Spoof Real SIM to SAM”
6. Then return to the main SAM menu and in the section "Method" choose manual mode(manual). Then in the same main menu, paste or type IMSI saved in the previous step. 
7. Connect your phone to iTunes. After the program has recognized the iPhone, double-click on "Phone number". The ICCID must match your SIM card, otherwise repeat the process.
8. Disconnect iPhone from iTunes. Disable or remove SAM. 
9. Reconnect iPhone to iTunes. The program will display an activation error, do not be alarmed, everything is fine, it should be so. Close iTunes and start it again. 
10. After all this, your iPhone is simply obliged to catch the network and the name of your operator should appear on its screen of the gadget. 
11. After this operation, iPhone unlock does not work push notifications... This is all easily fixable. The next time you connect to iTunes in SAM, click on "Clear push".
The only drawback of using this unlocking method is that it allows you to unlock your iPhone only on the SIM card of one carrier. In order for your phone to work with another SIM card, the entire unlocking process must be repeated again.
Now you can easily unlock iPhone 4, iPhone 4S and iPhone 3GS using the SAM package from Cydia.
By "unlocking" iPhone 4 (the so-called "unlock" procedure) means decoupling the iPhone from the need to use SIM cards of a certain operator. Depending on the country of purchase, iPhone 4 may be locked. tied to the network of a foreign mobile operator.
There are a number of ways to unlock an operator. Start by checking if your iPhone 4 is locked. You can check the unlock status yourself (your iPhone is locked or unlocked) at http://iphoneimei.info/
In addition, you need to know the version of the modem on your device. You can find it here: “Settings”> “General”> “About this device”> “Modem firmware **. **. **”
Depending on the firmware version (and, accordingly, on the version of the modem on your iPhone), you can use the following methods:
If your modem version is 01.59.00 - use the ultrasn0w utility. If you have modem versions: 02.10.04, 03.10.01, 04.10.01 you can use the method of “hardware unlocking” of the modem using Turbo SIM. Turbo SIM is a special adapter that unlocks the one tied to a specific operator mobile communications phone. For such models, the Gevey Ultra model is suitable. Be careful, the use of Turbo SIM is usually associated with many remarks, for example, the operator's USSD codes are inoperable, there may be difficulties with using mobile internet... If you decide to use Turbo SIM, stick to simple rules- choose the latest generations of Turbo SIM than newer topics better. Make sure that there is confirmation of the successful operation of your iPhone model (with your firmware and modem version) with a certain type of Turbo SIM. In total, there are three main Turbo SIM providers on the market, each of which works only with certain iPhone models... In the overwhelming majority of cases, to successfully use Turbo SIM, you will also need to jailbreak (“hack”) the iOS operating system.
If your iPhone 4 has modems of versions: 04.11.08, 04.12.01, 04.12.02, 04.12.05, 04.12.09 - Turbo SIM unlocking is not suitable for you, you only need to rely on official unlocking methods from a foreign mobile operator. They differ depending on the connection method and the term of the contract. A number of operators allow you to unlink in case of expiration of the contract, some operators provide such a service for money. After unlocking the operator, it is enough to connect the iPhone to iTunes and it will be activated to work with any SIM-cards.
Chinese developer Loktar San has presented a jailbreak method for jailbreaking an iPhone based on a new ICCID vulnerability. The SAM (Subscriber Artificial Module) technique allows you to unlock iPhone 4S and iPhone 4 that are contractually tied to cellular operators and have any baseband versions, including those made.
The SAM method was tested by the leader of the iPhone Dev Team with the nickname MuscleNerd, which confirmed its 100% performance. He unlocked the iPhone 4S locked to the American provider T-Mobile. Users also report successful unlocking of iPhone with firmware modems 04.11.08, 02.10.04, 04.10.01, 04.12.01, 1.0.13, 1.0.14 and 1.0.11 using this method.
It should be noted that this way has one significant drawback: unlocked devices can be used with only one SIM-card - there is no hot-swap of SIM cards. Therefore, iPhone owners tied to AT&T are advised to unlock contract devices. You can find out the details by going through.
Notes (edit):
- SAM does not cause accelerated discharge iPhone battery and supports push notifications like officially activated iPhones.
- Requires iPhone 4S, iPhone 4 or iPhone 3GS with jailbreak, which can be activated via iTunes based on iOS 5.0 or higher.
- Required latest version iTunes and Internet connection.
- You must know the cellular operator your iPhone is locked to.
The new unlock method is quite non-trivial and has 13 steps. In the near future, Loktar San promises to release an update to simplify the procedure. Further instructions on how to unlock iPhone 4S and iPhone 4 using SAM.
