    I've been trying to research this myself but it seems like most of the information out there is for the iPhone 3G or 4. Is it still possible to jailbreak and unlock it? How do I found out about the baseband/bootrom? I can't go to settings or anything because the only sim card I have is not for AT&T.

    I'm guessing I have the new bootrom, so it appears I won't be able to jailbreak & unlock the iPhone without rolling back to 3.1.2, however I don't have any SHSH blobs saved seeing as I just bought the phone.. does this mean that it is not possible at all to jailbreak it?

    You can JB from 4.0.1 and below. Problem lies in that you need to downgrade and only way to do that is having SHSH files saved. Did previous owner saved them? If no, you will have to wait for possible 4.1 JB.
