    A TurboSim is not an unlock! (!!!)

    It is a hardware that has the ability to fake a providerID.

    I don't think that Apple will explicitly block the TurboSim. All the times they broke the unlocks were because they were just updating their files on the flash. Breaking the unlock was "collateral damage."

    To block the TurboSim they would need to explicitly check something else than the ProviderID on the SIM. Anyway, that's my 2 cents, the fact is that 1.1.3 breaks the activation, so even if you have a TurboSim, you won't be able to use the phone until it's activated again... Hopefully that should be easier than a full software unlock.

    Cheers,
    BK

    Almost

    The easiest break would be a compare to make sure that the IMSI/ICCID pairs returned are always the same for every request, which is not applicable as of today.

    so does that mean that turbosim users should be able to use their iPhones once a new activation mechanism is found for 1.1.3?
    iPhone week 46 FW 1.1.2 BL 4.6 unlocked with GUNLOCK => TurboSim is now in the trash
    Carrier Optus Australia, everything just works!

    it depends on the way the check might be implemented, if it will be changed. I can think of a few ways where I'm pretty sure they will prevent turbosims and similar adapters from working in the future, at least it might be necessary to a change some files on the iphone to make them work once again.

    Have a look at the way they work and you will see that it's easy to break them.

    It's not only a question of reprogrammability but of workflow, e.g. order of initialization, priority etc.. It's by design that the baseband firmware get's core control and the credentials are taken from the SIM card. Nevertheless, the checking ("hey, are you a valid SIM according to apple ?") is a really weak one and can be improved easily without a possibility for the turbosim to react on this. Therefore, the turbosim can only work if it get's initialized and gets somehow involved in the whole communication chain. And this is were a break can occur in firmware updates, if it's no longer possible to fake the network information.

    This was a little bit different in early days with only AT&T cards being allowed before firmware 1.1.2, meanwhile lockdown daemon interaction with baseband is more complex when it comes to the iphone's decision whether it's a valid card or not.
