    Take our advice -- please -- for your own good -- just wait right now. I know you want something to work, but the more you grasp at straws the more you're just going to ensure you end up in another uncomfortable situation that we can't help you out of.

    Advise taken lol
    I was sooo happy when I found this iPhone so clean and new, it had a screen protector since day 1 and spent all his life in otter box. Since It was so old baseband and firmware I thought THIS IS IT !!! white 32g not a single scratch.. I should have instructed me better prior, but well, Im still learning !
    Its for sale now.

    Thank you so much buddy for your QUIICKK !! help and support

    I'd hold on to it unless you already have a different device that's in a better state for jailbreaking/unlocking -- the odds are slim you'll be able to find a phone that's going to be easier to jailbreak or unlock than this model any time soon (any new iPhone 4 is going to be a nightmare to unlock, and may be excruciatingly painful to jailbreak if it's on 4.2.1) -- and the more likely case is that newer software revisions or updates will come out making any new phone you get if you try this again even more difficult than the existing.

    Since it works on 3.1.2 or 3.1.3 now, it's still quite functional as an unlocked phone. If you hold on to it now, make sure to back up SHSH files for the current iOS revisions and any of the upcoming ones, you'll put yourself in a very good position to get back on the jailbreak and unlock train with the device.

    No problem -- I'm sorry that the current answer isn't very fulfilling, as I know how frustrating it can be to have few options that really meet what you'd like -- but as mentioned above, if you hold on to the phone for a few months, the odds are pretty good in your favor that a jailbreak and unlock will be developed for this model and that you'll be able to hop onto the jailbreak train.

    Dude I buy iPhones everyday and sell them. Cant post the reason here but it dont matter anyways.
    So I try to learn as much as I can. However; I still dont know what SHSH files are... I know you feel like slapping me on the back of my head right now.. I would too.
    So, tomorrow Im supposed to get 2 3GSs and now that I know its not all about firmware and baseband, is there a way to know what bootrom and iPhone has other than through System Profiler in DFU mode??

    As far as the Phone dude, Im tied up to a T-Mobile contract, otherwise Id be with H2O man, I gave my brother a 3gs unlocked when he had TMo and now he doesnt even need the iPhone jailbroken dude ! he upgrades through iTunes like if he had Att. I sold my green 32g one, and bought and i4.. dude, I only surfed the web a little on wifi, and had to let it go man.

    Well, I have to thank you again !!

    - system profiler + phone in DFU mode is the sure way to confirm bootrom version of the device.

    - tinyumbrella will tell you if the device has any SHSH.

    - You can search the forum for SHSH. Plenty of explanation for that

    Don't worry. SHSH is confusing for most people and understood by very few. Since I've only ever given a top to bottom explanation once or twice, I'll do it again for your benefit.

    For an iPhone 4, when you go to restore an iOS to the device, a chain of events happens. For the purposes of this conversation I'm only covering the SHSH portion so anyone with insight into the process will likely note I'm skipping key bits of the restore process -- but I'm really only tackling the SHSH here so, hush.

    1) You tell iTunes to restore an iOS to the device.
    2) iTunes downloads the firmware.
    3) iTunes generates a hash, based on the firmware file that it just downloaded. This hash is unique per iOS revision. E.g., the 4.0 hash is different than 4.0.1, etc.
    4) iTunes sends this hash and your device's ECID to Apple and asks Apple if Apple approves you restoring this specific firmware on your specific device.
    5) Apple's servers either respond yes, and provide you the valid SHSH (this only occurs if Apple is still signing the iOS revision, and presently Apple is ONLY signing 4.2.1), or they respond no, and you get "The device is not eligible for the requested build".

    The funny thing is that Apple did not implement this very securely, as the SHSH is generated on a static (per device) number, so this means that every request for the same iOS revision for the same device will always return the same SHSH. This makes the system susceptible to a 'man in the middle' attack, where the favorable response from Apple (the 'Yes, you can restore this firmware') is caught in transit back to iTunes and stored. In the future, even if Apple is no longer signing this version of software, the saved SHSH allows TinyUmbrella to act as the Apple server, responding back to iTunes with the 'Yes, you can restore this firmware', even if Apple is not signing it.

    So, the key here that most people don't understand is that the SHSH is specific to each device, and to each iOS revision per device. This means that no one else's SHSH will work, it is truly unique to your specific phone. Beyond that, you can *only* obtain the 'Yes, you can restore this firmware' response if Apple is still signing the firmware. Most commonly, users think that if they are running a specific firmware, they can obtain an SHSH for that firmware. This is 100% INCORRECT. You can ONLY obtain an SHSH for firmware that Apple is still signing, as the SHSH itself is nothing more than the store response Apple sends that allows the .ipsw to be 'personalized' for your phone, which is required before the iPhone will accept the firmware. If Apple is not saying 'Yes' to your revision of iOS, you cannot save the 'Yes' response, as they're not giving it.

    So, I hope this helps you understand what the SHSH is, why it is needed, how it works, and some of the more common misconceptions.

    Note that this does not have anything to do with the baseband SHSH that is included on newer iOS revisions, but this is almost identical to how the soft-SHSH is stored for the 3G and 3GS on iOS revisions 4.0 and higher (as iOS revisions 4.0 and higher have a software based SHSH check implemented for the 3G and 3GS models.)

    The road block is to have an un-tethered jailbreak.
    Im googling a tutorial to jailbreak it but, all I find is downgrade tutorials!


    As for the SHSH I got it! Easy to understand explanation man !! thank you so much !!
    Btw, I have tinyumbrela but never used it lol
    So SHSH are not saved on the device, right? I though that was what "make my life easier" was for.

    Make my life easier saves the SHSH with Cydia on a server run by Saurik.

    Tiny Umbrella can retrieve these SHSH either directly from Apple (if they are still signing them) or from Saurik's server.

    Technically a partial SHSH for the currently installed iOS version is stored in the NOR, on your phone. There are no tools to extract this (yet).

    So basically it'll be a good idea to just save SHSH for every iPhone that passes through my hands, right?
