    Default Is it possible for a carrier to ask Apple to re-lock an iPhone 3G?

    Is it possible for a carrier to ask Apple to re-lock an iPhone 3G?

    In my country (Australia), iPhones are sold locked but official unlocking is available for a fee. If somehow I manage to convince my carrier that I obtained a replacement phone and get them to unlock the second one without fee, is it possible for them to ask Apple to re-lock the first one?

    What makes you say that? What happens when Apple has the phone in their hands?
    Did you mean that if your phone is replaced under warranty, the original phone (the broken one) will automatically be re-locked, but other that that it's not possible to re-lock an iPhone (even if the carrier requests it to be re-locked because there was a mistake in the unlocking request)?

    It can definitely be done. They do NOT need your phone in their hands.

    It happens much the same way that the unlocking happens. When you connect your phone to iTunes, it checks a server for your phones device ID. Theoretically, your ID can be tagged as needing to be locked as opposed to needing an unlock.

    I am not too good with baseband stuff, so please bear with me, but is it possible to obtain the NCK that is given via iTunes for the unlocking? I mean, i would imagine so, I just don't 100% know for sure. If someone looks into it and sees where they store it (since it needs to be sent at every boot, I believe), then they probably cannot re-lock your because (if you are jailbroken), you could probably set up a launchdaemon to send the AT command that it normally uses to send the NCK. Again, I don't know if Apple would even bother re-lcoking a phone like this, and I do not know much about the baseband, but I don't see why this would not work.

    The NCK unlock code is sent once. It transforms your seczone tokens once. The seczone is not touched by baseband updates -- only by the NCK unlocking code. The NCK code is not sent on every boot, and it's not stored anywhere.

    There is in theory a software route by which they could un-transform your seczone tokens back to their locked state, but we have yet to see that implemented by Apple.
