    Default How to check if phone has been unlocked from Carrier

    First of all

    Sorry if this is a double / triple and so on post, Googeled and checked these forums and could not find the info I was looking for.

    So I got myself a 3Gs that was Carrier locked when I bough it from a friend, I was told it would later be unlocked from the carrier, he has now told me it should be Carrier free.

    The thing I wonder is if there are any way for me to check this without reinstalling the phone? I guess it is at the activation part of the phone after a reinstall, when iTunes verifies the SIM-card that is checks Apples servers if the phone is free? And free it up if it should be.

    So, do I need to reinstall / upgrade the phone to check this, or is there a more simpler way?

    Currently on 4.0.1 with ultrasn0w unlock and running Comex JBme.com

    Thanks in advance! and if this is a old question in a new thread, just slap me

    The only 100% accurate way to check this is to restore.

    if you have a SHSH for 4.0.1 or 4.0 then you should be able to easily restore and test this without losing your ability to unlock and jailbreak.

    Try putting in a SIM card from another network.

    If it loads up then you know it's unlocked.

    This will *also* work if the iPhone has been hacktivated (jailbreak + lockdownd patch). Which is why your method is not a good recommendation.

    In my testing and experience, the only accurate way to determine if an iPhone is officially unlocked is to restore it.

    Actually if you know that your iPhone is still unlocked (that is it was never unlocked by iTunes) you can do it without needing to restore. Works even with hacktivated iPhones (need to remove hacktivation temporarily).

    The key is to force iTunes to attempt to activate the phone (unlock is done as part of official activation), using the same trick as the one employed to make push certificates:

    If you have Ultrasn0w installed, remove it, or it will interfere.

    If your iPhone is hacktivated, you need to remove the hacktivation data: SSH to the iPhone and remove or save all files and folders in "/private/var/root/Library/Lockdown" (this will deactivate the iPhone), but you still have SSH access to it. An alternative is to just rename "Lockdown" to "Lockdown.save" just in case it still not unlocked and you need to hacktivate it again.

    Reboot the iPhone.

    Put a different SIM card (from a carrier that is not the original one) and plug to iTunes. It will deactivate the iPhone (if not already deactivated). Remove the USB connection and plug again and it will activate.

    If Apple has set it to be unlocked, it will do so while it's being activated and it will also activate the non-official SIM card.

    If it still not unlocked and hacktivation is required: reboot, SSH and rename the saved directory back. Reinstall Ultrasn0w if needed.

    Thanks very much, I suspected that something like this might be possible

    One additional point (especially important on 4.x) - make sure you have turned off any iPhone passcode before you try this. Othewise iTunes won't reactivate the iPhone and (at least under 4.x) you will have to restore the iPhone to get it working again.
