Week those from Apple have completely blocked the solution for decoding iPhones through SAM and I noticed that many of you still do not understand what this entails. I start by telling you that these two tutorials: 1, 2, are no longer valid, I took them out of the jailbreak and decoding table, and my recommendation is to forget about them because you won't be able to use them for anything soon. Practically NO ONE it can no longer use SAM to make a new decoding, but the decodings made and saved they can be redone with the help of this tutorial.
If you have not saved the decoding made with SAM, then you can save it using this tutorial and you can use it in the future, but if you lost it NU you can redo it without the saved files as long as you had it active. Changing data from Lockdown files IT IS USELESS because Apple has other data for decoding in its servers, and changing the ICCID of the terminal or the card code does not help at all. If you change the current card of your iPhone lose the decoding done with SAM, so take care of the card, otherwise you risk being left with nothing for a very long period of time.
SAM Unlock it is lost for those who failed to do it, it is still usable for those who saved the decoding, but only as long as they have the card on which the terminal was decoded. Unfortunately, the blocking of this decoding solution has returned everything to the state it was in more than a week ago, that is, iPhone 4 with iOS 5.x baseband cannot be decoded at all, but iPhone 3GS can be decoded with iPad baseband on any version of iOS, and the iPhone 4S can be cracked with Gevey Ultra S on any version of iOS.
I hope I've clarified for you, if you have questions that are not covered by the article, then please leave them in a comment.
