    Default Upgrading to 4.2.1 without locking up my phone

    So in this tutorial, iClarified - iPhone - How to Jailbreak and Unlock Your iPhone 3G Using RedSn0w (Windows) [4.2.1], it says that it gives you an option of updating your baseband to 06.15 does that mean if I refuse it will leave my baseband and unlock alone?

    No... Definitely NOT.
    If you do this you will definitely lose your ability to unlock.
    The reason is that when you do it this way:
    1. You use iTunes to update or restore to 4.2.1 with a regular IPSW. This step will upgrade your baseband.
    2. Then you run redns0w to jailbreak. At this point it is too late, your baseband is already updated.


    Don't be confused by the "update baseband" feature of redsn0w, that is a totally separate thing.

    Custom IPSW is the ONLY way to preserve your baseband on a 3G or 3GS. We ONLY recommend PwnageTool for making custom IPSW.

    As I said, we ONLY recommend pwnagetool (Mac only)

    You can try your luck with sn0wbreeze (windows only) but there have been lots of reports of serious problems with sn0wbreeze - which is why we refuse to recommend it or provide support for sn0wbreeze here.
