    Question [iPlus] Effects on Restore & Update AFTER unlocking?

    I was wondering what happens to the iPlus unlocks in two different situations:

    If I for any reason had to restore to 1.1.4 would the unlock be erased (I Know the JB would be but what about the unlock)?

    And when new firmware comes out what will an update do to the baseband on my phone?

    Will it simply relock it so that the phone will ONLY work with an official SIM that is officially activated OR will it mess up the new baseband and stop working? I realise we can't be sure what Apple are going to do with the way they put the next update on the phone but if it is updated the same way 1.1.3 and 1.1.4 were then what would happen to the lock and baseband?

    I think these are important questions which I could not find in the big iPlus thread and having them answered will help avoid lots of questions when people have restored or updated!

    Thanks.

    ans #1) yes, it will. but hey, just run iplus again to unlock it, duh..

    ans #2) yes, it will lock again. heck, who cares (read: i dont care) if apple release new firmware with new baseband comes with it. for me, firmware is just like another software,baseband is the driver comes with it, and bootloader is BIOS. u mess up with software and drivers? no worry, just restore it.

    if u have the 1.1.4 BB (i think u have since you run iPlus) then a restore will not reflash
    the BB unless u restore to a higher firmware( 1.1.5? 2.0?)
    so for now if you just restore again to 1.1.4 , you will only need to jailbreak
    i used zIphone for this

    restore the same firmware to an existing unlocked phone will:

    - erase everything on phone.
    - phone will be jailed and not activated (you need to JB+ACT again using the tool of your choice be it iPlus or ZiPhone or whatever)
    - baseband will be the same therefore no need to unlock again.

    When a new firmware comes out and if you upgrade to new firmware, it will:

    - put new firmware (OS) on the phone
    - new OS on the phone means your phone is jailed and not activated (you have to JB+ACT again with new tool or same tool depends on how the new firmware work)

    - if there is a new baseband associate with new firmware, it will update the baseband to "higher" version.
    - baseband version change requires unlock most likely using a new unlocking tool.

    - new firmware so far does not upgrade bootloader

    I want to be clear - a new firmware update will simply relock and deactivate (and re-jail the phone) and NOT cause any problems with a new baseband such as corrupting it and messing up the IMEI?

    yes - a new firmware update will re-jail and deactivate.

    so far a new firmware also include new baseband version so it will also update your baseband version and therefore relock your phone.

    Corrupting baseband and messing IMEI happened with the transition from 1.0.2 (that was unlocked with iUnlock / unlock-fast.pxl / old old anySIM) to 1.1.1 - After that period, new unlocking method does not corrupt the seczone and therefore no more problem

    Ok so in theory if you have an official iPhone contract you could upgrade as soon as new firmware is out and the phone would work perfectly?

    I know the unlock will be gone but if you don't need it and your officially activated then you can upgrade without any problems which were caused by the iPlus unlock?
