    Default anySIM suffers from being open source

    When people claim that IPSF is better unlock than anySIM because it does not brick the iphone and because it can be downgrade and keep the phone unlocked. My question is… was the dev team solution an easier target from apple because it was open source?.
    Is it IPSF better? or is it just that IPSF was simple ignored by apple (this time) because without the source code it is harder for them to fight back? Does this show that apple created an upgrade that was design to brick phones that used specifically anySIM instead of fighting all unlocks methods?

    I also had the same thoughts...!

    Could it be possible that the IPSF guys have the decryption code for the baseband that only apple should have? I suppose IPSF doesn't relay on the empty memory bug.

    All and none of the above.

    Lots of familiar names here from the land of TiVo......


    I personally think that the IPSF unlock method is close to how Apple will do an unlock when required to do so after the end of contract period. This involves setting a bit in the EEPROM to signify an unlocked phone. This is why upgrading the broadband still leaves the phone unlocked but unable to be used without an AT&T SIM because you cannot bypass activation. The anySIM method involves an actual change to the broadband code which is detectable.

    What we have to look at is how we think Apple will unlock the phones at the end of contract ( which in Europe they WILL be obliged to do - and it is arguable that they cannot be legally locked in the EU when sold as an unsubsidised phone anyway. ) I believe this is a single step process that will do two things - with existing type phones when you put the "wrong" SIM in a locked phone you are able to put in an unlock code which is generated for your unique IMEI, this then will write a bit into the phone removing the provider lock, I think the process will be the same for the Apple phone or they will provide a program which you run via iTunes which will do much the same thing - I think this is how the IPSF guys are providing unlock - the second will have to be another bit ( or product code ) change in the EEPROM which will signify to iTunes that the phone does not need to be activated for that SIM and that it will just work with any valid SIM. As both of these processes are outside the firmware they will survive upgrades.

    Now what are the approaches to hacking this - well arguably the entering of the unlock codes would be a valid approach, not to patch but to reverse the algorithm required and make your own code gen ( this is how the vast majority of Nokia phones are unlocked. ) but it is now the activation that is the issue, if Apple are doing what I propose above then they do not have to show their hand until they are obliged to unlock the phones for any network ( >18months or so. ) In this I believe that the DVDJon method shows the most promise to faux activate. When a genuine Apple unlock is shown and *if* it works as I propose above then your phone will already be cset to auto activate fine with iTunes.

    Or we have to independently come up with a method that is similar to the Apple/IPSF unlock method if it is not unlock code based.

    No how can/will Apple fight back? Apple would have a hard time arguing that a phone that has been unlocked using their own method would invalidate warranty - the phone is designed to be unlocked that way! As the anySIM method is not the way they would unlock the phone ( by patching firmware ) they can ( justifiably? ) argue that you have tampered with their phone and invalidate the warranty. However as there supposed to be no unlocked phones out there yet Apple could be justified in resetting the unlock bit on any phone for the next two years or so - and also they do not need to change the activation in iTunes either for the same period.

    Ho hum.

    Rgds,

    The IPSF method is too "clean" to be a method without some insider knowledge. Now I shut up... People also seem to forget that although it won't "brick" your unlock phone part if you downgrade to 1.0.2, it doesn't work with FW 1.1.1 either.
