    Exclamation CONFIRMED: Data Corrupted By AnySIM/iUnlock 1.0.2 Is Recoverable, IPSF not.

    Wow. what a turn of events. It looks like the data overwritten by the old anySIM/iUnlock can be re-produced. while IPSF might not be the jesus unlock afterall.

    According to MuscleNerd from the iPhone-elite team, talking about his seczone Encryptor/Decryptor code:

    that is enough to revirginize an anysim 1.0x unlock.....it is not enough to revirginize an ipsf unlock....specifically, because the "token" at 0x400 has been zeroed out by ipsf....and is not recoverable unless you have a backup nordump. if you have a backup nordump before ipsf, then this code will let you revirginize (once placed inside a custom baseband to to the nor writes.
    it can be used to properly encrypt data into the seczone. In the anySIM 1.0x case, it can be used to properly encrypt the virgin lock table into the seczone (the virgin lock table is the same for everyone, but uniquely encrypted per iphone...this code fixes that)
    In the IPSF case, it can be used to properly encrypt the virgin lock state...the same as with anySIM 1.0x. But it cannot be used to properly encrypt the virgin token, because that virgin token has been wiped out by IPSF. With anySIM 1.0x, the virgin token is still there, untouched. With IPSF, either you have a nordump of the seczone before ipsf, or it's lost....unless ipsf saved it and you can get it back from them
    EDIT: Difference between anySIM 1.0x and IPSF

    * The anySIM 1.0x unlock inadvertantly convinces the Apple baseband code to rewrite the lock tables at seczone+0xc88, away from their virgin locked status. That's okay as long as the anySIM 1.0x patch to the baseband is still in place, because that inconsistency is ignored (by the patch). The anySIM 1.0x unlock does not change the "token" at seczone+0x400.

    * The IPSF unlock intentionally rewrites the lock tables at seczone+0xc88, away from their virgin locked status. They also zero out your 'token" at seczone+0x400. The zeroed-out token combined with the lock table changes convince your iPhone it's unlocked because of an RSA bug that Apple has in their code (RSA is used on the token).

    To be make everything clear. Everybody is speaking about AnySim and iUnlock. But there is another application that *many* users have used: unlock.app (the 20 minutes unlock procedure)

    Does this application use the same technique like AnySim and iUnlock? Will the virginizer also work with that application?

    iUnlock is the command line tool used by unlock.app.

    Why do you need to revirginize if you unlocked it forever using IPSF ??

    Doesn't make sens to me.

    I am pretty certain that there were only two software-based unlock mechanisms, although they came in different wrappers (the hardware unlock people might possible have something slightly different; I don't know).

    All the free solutions like AnySim were derived from the same low-level iUnlock code. The only other solution was the non-public IPSF.

    Since the iUnlock code was available in source form, as well as acessible inside the AnySIM GUI tool, there are probably various variations around but they all do the same thing when you get to the nitty-gritty end.

    If I virginize my AnySim102?-unlocked phone with the described method here: http://hackint0sh.org/forum/showthread.php?t=12052, could I also get problems when the bootloader gets updated?

    Edit:
    Because one of the steps is to run IPSF (pointing to the server at 129.21.116.152)..

    So can somebody explain what this means in practice for those who have used IPSF? I also support the dev. team. with donations and spirit, but needed a quicker solution this time. I suspect many people felt the same.

    What are the implications for the future of having used IPSF to unlock?

    Thanks
