The inevitable happened and Apple blocked the possibility of decoding any iPhone from any network. This blocking has been announced for a few days, but now it is 100% official and no one can do decoding for AT&T for example or for other networks that became unblockable a week ago. It was normal for Apple to do this since tens of thousands of iPhone owners desperately sought to decode their terminal as quickly as possible, and in the end it was proven that everything was done without Apple's knowledge, so unofficially.
Now the only problem has to do with the recoding of the terminals, which Apple could do if it wanted to. Personally, I don't think that Apple will do this, but if it does, then those who have done the decoding can save it and keep it for the future without problems. If you do an activation through iTunes at some point, then you lose all the decoding and the money you paid for it. Those who do not have decoded terminals but paid money for it will probably get their money back.
I will write a tutorial that will teach you how to save your decoding. NOBODY makes decodings for AT&T or other networks that were undecodeable until last week, be careful!
UPDATED: Tutorial for saving the activation you have here. It is important to install SAM and click on backup activation.
