A few years ago we were often forced to unlock an iPhone to use it. Since, it is less useful in France where you can ask unlock a device after 3 months with his operator without paying. However, in some cases this may be still useful to override the operator.
course, why we must have a jailbroken iPhone which is simple if you are still under iOS 5.0.1 even with a 4S with redsn0w 0.9 .10 b7 .
Following is a simple procedure discovered by Loktar_Sun via a flaw in the iPhone Baseband all. We must have the latest version of iTunes and put the SIM you want to use in the iPhone before continuing.
Loktar_Sun , a Chinese hacker, just to make it possible for any unlocked jailbroken iPhone iOS 5 and above, following the discovery of a vulnerability in the ICCID. With patch Sat (Subscriber Artificial Module), available for free on Cydia, you can now easily unlock your iPhone jailbroken 3GS/4/4S all Baseband !
This is great news for iPhone owners locked to an operator and not having the opportunity to officially unlock their device. And for good reason, with this tutorial and Sat patch, you will be able to unlock virtually any jailbroken iPhone (iOS 5/5.0.1/5.1), Baseband and all for free! The feat also been confirmed by MuscleNerd , famous hacker of the Dev Team, who managed with this technique to unlock the iPhone 4S.
It may be that push notifications stop working after this procedure. Do not panic! You can easily restart them by connecting your iPhone to iTunes and then go to settings on your device and Sat press” Clear PUSH “.
Warning, this method allows to use only the SIM card installed in the iPhone during the proceedings with Sat You can not switch between your SIM cards without repeating the operation from the beginning. This is not a total désimlockage like that you can formally propose Apple or your carrier.
