    Default Some thoughts/questions about unlocking 1.1.2 iphones

    OK its clear that as until now iphones with fw 1.1.2 and new baseband and bootloader cannot be unlocked.

    But is it possible to downgrade both fw and bb to an older one and then unlock so that we can use the iphone as a phone (even with that old firmware) and not only as an Ipod?

    There have been a few guides here that describe how to go from 1.1.2 to 1.1.1 and then to 1.0.2. If someone does this and then also downgrade bb to the old one, will it be possible then to unlock the phone using the 1.0.2 unlocking procedures? If not what would be the problem in doing so?

    I think all of the existing tutorial for downgrading 1.1.2 to 1.1.1 to 1.0.2 and downgrading baseband are all only work for NON-out of the box virgin 1.1.2 iphone.

    That's mean at this moment, we still can't do anything for the virgin 1.1.2 out of the box iphone

    That's what I think too, but what I am trying here is to understand why a downgrade of both fw and bb and then an unlocking with the relevant tools wouldn't do the job....

    Downgrading firmware -> Yes
    Jailbraking -> Yes (with downgrading to 1.1.1 or 1.0.2 first)
    Activate -> Yes (with downgrading to 1.1.1 first ..)

    Unlock -> no !!

    even you downgrade the firmware to 1.0.2, the baseband will stay at the new one. You still can't erase the baseband to make the phone unlockable, since the new 1.1.2 iPhone OTB comes with new bootloader, which looks like it make the bb writer unworking ..

    That's the pain ..


    so .. what i was trying to say is .. we can't rewrite bb since the new bootloader arrived ..

    That's mean we can summarize the different between a virgin 1.1.2 OTB iphone and a 1.1.2 iphone which is upgraded from 1.1.1 with the following:

    Virgin 1.1.2 OTB iphone --- 1.1.2 fw + 1.1.2 BB + New Bootloader
    1.1.1 --> 1.1.2 iphone --- 1.1.2fw + 1.1.2 BB + Old Bootloader

    Am I right?

    Exactly



    BTW .. I can't tell you certainly that what method should be used to downgrade it too 1.1.1 .. some of them said only 1.1.1 to 1.0.2 does need DFU mode, just using shift+restore from itunes, but some said that just make 1.1.2 going to DFU mode first then using shift+restore method to downgrade 1.1.1

    is it not possible to completely flash all software (either 1.0.2 or 1.1.1) to a new iphone in order to erase all 1.1.2 crap and have a fully unlockable phone?

    What I mean is since the hardware is the same, why not uploading an old software and do the job...(like uninstalling vista and installing xp on a notebook I recently bought )

    U are right, u can erase all the data about 1.1.2 and flash a 1.1.1 into it. But there is a bad guy call Baseband which cannot be flash out easily, and that bad guy baseband is actually the core for deciding the phone is locked or not.
