    Ok, well he can always use TU to preserve the baseband if it puts him at ease. A factory unlocked phone means you don't use ultrasn0w which you probably aren't using right now. So do what Yeow said, just update it and jailbreak it.

    Or do the update with TU to put yourself at ease then. Same thing same process, update and jb.

    What!!? You said "update it", but my device was shipped with 4.1 already installed (which I mentioned in my 1st post). I was simply asking what you expect me to update it to (maybe there was an update I was unaware of)? How does that make me paranoid about the baseband? I haven't even mentioned the baseband or factory unlock in my last 3 posts.

    THANK YOU! That's all I was asking. Do I need the 4.1 ipsw like I used to when jailbreaking my touch with redsn0w?

    Sorry for the misunderstanding. We were under the impression you weren't on 4.1 yet.

    You will not need a stock firmware to use the jailbreak tools.

    Since I just got my iPhone 4 a few days ago, this is my first time connecting it to the computer. Should I register my iPhone with itunes?

    Yes, uninstall the launcher. Once you click Yes to Make my life easier, all future shsh blogs will be saved and you need not worry about it until you need to do a restore

    Register your iphone is good, in case if you lost it, you can prove that you are the owner of this iphone.

    They're SHSH blobs and you need them if you ever have to go back to a previous firmware version (e.g. if you upgrade by mistake). Otherwise iTunes won't let you restore to a previous version. Google "SHSH blobs" and you should find lots of info on what SHA-SHA blobs are exactly.

    Ok I actually did a bit of searching before, but all I could find was "how to backup your SHSH blobs" or pages that simply stated what backing up your SHSH blobs would achieve. Anyhow, I did a bit more advanced searching and found this good explanation:

    SHSH Blob is a signature file which is verified against Apple Server to verify the the iPhone is running the latest version of iOS. If for some reason, when you are try to restore to a previous version, Apple will not allow you to restore it becuase, you are trying load a older version of iOS. To make this possible, we need to send a request to a different server (Local or designated) which sends a SHSH blob (which was saved by you) back to iTunes faking that its the current version.
    Source: What is SHSH & How is it important? & Few FAQ's | MacHackPC

    I noticed that backing up my blobs in Cydia backs it up to the Cydia servers, but how would I go about backing them up to my own computer... yknow, just in case.

    Did you look in the "Advanced" tab? On my Mac, at least, there is a place to specify where to save your SHSH blobs. I store mine in /Users/RiotNrrrd/.shsh.

    Sorry ... the "Advanced" tab in TinyUmbrella 4.1.13.

    Yeah just noticed, it saves it to: C:\Users\[username]\.shsh

    Why does is save 2 files?:
    - xxxxxxxxxxxx-iphone4-4.1.shsh
    - xxxxxxxxxxxx-iphone4-4.2b3.shsh <-- what is this one for?

    Also, when I start TinyUmbrella, I always get this error:
    Cannot Start TSS Service
    DO NOT TRY RESTORING YOUR DEVICE!!!
    System(PID:4) must be killed!!

    It saved your SHSH blobs for both iOS 4.1 and iOS 4.2beta3. Don't worry about it. Be glad

    TinyUmbrella tries to run a little mini Web server on your own computer so it can intercept iTunes' attempts to do an E.T. Phone Home to Apple's update server(s). If you are running a personal Web server on your PC - or are running Anti-Virus/Firewall software that is listening/using that port (port 80) - then you'll get this message.

    If you aren't restoring - i.e. just getting your SHSH blobs - you don't need to worry about this msg.

    Eventhough you have the shsh blogs for the beta version, you don't use it unless you are a developer.
