You might already have unlocked your iPhone 4S or 4 using SAM unlock method which was released very recently. The most significant trait of SAM unlock is that you can perform it on any iOS versions and no matter what its baseband is. Before the availability of SAM iPhone unlock, it was pretty hard to get iPhone 4S unlocked since hardware unlock tools like Gevey SIM, TPSIM etc have charged some amount to get it done. Major thing you should have noticed with this SAM unlock is that, your iPhone 4S/4 must be jailbroken, since the SAM package will install via a cydia repository. That means SAM is an iPhone 4s/4 jailbreak unlock. If you haven’t unlocked your Apple iOS device, here you can find the complete step by step procedure.
There is another bad news spreading all across the iPhone unlock community is that Apple is trying to block the SAM unlock by fixing their activation servers and we have got the confirmation from musclenerd, member of iPhone Dev Team, via Twitter.
But no need to worry much about it. When the developers came with the SAM package, the jailbreaking giants from the iPhone Dev Team had updated their most popular iOS jailbreak tool redsn0w to 0.9.10b8 for saving (backup) the unlock activation tickets that generated while performing the iPhone unlock using SAM package. According to musclenerd those tickets are still working event though Apple fixed their activation servers. You can download redsn0w 0.9.10b8 for Mac and Windows from the links given below.
