    If you mean iOS 4.2.1 (why do so many people write it as 4.1.2?) then yes via PwnageTool 4.1.3 - see Dev-Team Blog - Ultra-recycle
    specifically the section that starts with:
    This PwnageTool also contains a 4.2.1 bundle for iPhone3G owners…
    Procedure is the same as described in iClarified - iPhone - How to Jailbreak Your iPhone 3G Using PwnageTool (Mac) [4.1] - just use pwnagetool 4.1.3 and run pwnagetool on iPhone1,2_4.2.1_8C148_Restore.ipsw from http://www.hackint0sh.org/f127/22056.htm to generate a custom IPSW.

    Then unlock with ultrasn0w http://www.iclarified.com/entry/index.php?enid=4253

    Finally, I recommend you install SAM http://www.hackint0sh.org/f204/194306.htm and ensur ethat the phone is wildcardactivated. You can then uninstall SAM again (if you want) this will make sure you don't have battery problems.

    Could you tell more about this SAM? I don't have problems with the battery but I'm interested and have never come across this in any topics.

    Edit: nevermind. I was hasty. You had a direct link to the topic.

    hello again, after following all the steps I now have a bb 5.15.04 (I made sure not to choose a bb update in redsn0w). Is this why now Ultrasn0w won't work (no carrier signal)?

    is there a way to fix this?

    thanks

    This is something you propably would have found out if you would have googled a bit but yes you can't unlock 5.15.04 - period. Or at least for now. You can try to upgrade to iPad baseband but that is something that I won't recommend! At least get to know the risks first!

    I just don't understand why the bb changed! Anyway, I'm aware of the risks and I have updated to 6.15.

    Thanks for your help today.

    This is because you DID NOT use pwnagetool. Only pwnagetool custom IPSW can prevent baseband update on a 3G or 3GS. I did recommend pwnagetool.

    Redsn0w is NOT the same as pwnagetool. They work differently - don't get them confused.

    When you restore original IPSW downloaded directly from Apple, any baseband updates contained in the IPSW will always be applied.
