    Question [IPSF] Does it keep 2.0 unlocked ?

    Does the iPhone SIM Free unlock survive the upgrade to the 2.0 firmware and work?

    Or does it require Signal.app like on 1.1.4 - which is impossible until the jailbreak is out (and when that is out so is the unlock!).

    I have not seen any threads about IPSF and 2.0 so if anyone knows or has tried it I would like to know!
    iPhone US 8GB
    FW 1.0.2--> iUnlock--> iPhoneSIMfree--> 1.1.1 --> 1.1.2--> Soft upgrade 1.1.3 --> 1.1.4 using signal.app
    iPhone UK 16GB
    FW 1.1.3 OOB --> 1.1.4 --> iPlus 1.2 unlocked!

    <----If I helped you out, rep points are always nice (thanks for that idea!)

    Doubtful due to the fact that there is a new baseband modem. I am not risking my iPhone for it. Sorry

    Here are the facts:
    - Apple has records of which iPhones have been activated through AT&T. They can bring up this information based on your serial number or phone number AT THE STORE or OVER THE PHONE

    Well, even if there is a new modem firmware tied to the 2.0 upgrade, that should not affect the lock/unlock state of the IPSF unlock. The original post in this thread asks the right question -- will signal.app work with the new modem firmware and thus allow a faux-activated, first-generation iPhone to work with a new SIM after a 2.0 upgrade.

    Once the dev team's pwnage allows activation access to these first-generation iPhones, I'm sure a few guinea pigs will test out how the IPSF unlock survives (it should survive) and also whether signal.app (or a re-coded version of such a process geared to work with the new modem firmware) lets the phone recognize a non-ATT SIM.

    (In other words, I'm not disagreeing with the above quote, but if the stop/restart process undertaken by signal.app can be re-coded to work with the new modem firmware then it is quite possible that an IPSF phone should work after being upgraded to 2.0).

    The IPSF unlock relies on an exploit in the 3.9 bootloader. Baseband version of the phone does not matter. There should be no reason the IPSF unlock shouldn't stay intact. The signal.app basically sends the unlock command 'AT+CLCK="PN",0,"00000000" to the baseband. I think it was version 1.1.3 and later that needed the signal.app because the baseband would re-lock after every reboot, so you would have to issue the unlock command again after you rebooted.
    Anyways, a neutered bootloader (both 3.9 or 4.6) does not require the signal.app since the lock checks are by-passed.

    So, yes, the IPSF unlock should survive. If you have a neutered bootloader via pwnage, you probably won't need the signal.app anyways. Your phone will essentially be unlocked two different ways which is fine since they don't conflict with eachother.
