    Question Help with 3G jailbreak and unlock
    Hey folks, been away from the iPhone scene for a while. Just got a 3G for my wife.
    It has the following:
    4.2.1 (8C148) firmware
    05.15.04 BB

    I need to unlock this for use on T-Mobile. I have searched the forums.
    Any assistance with this would be appreciated.
    If I have helped you...please say Thanks....

    If I have not....don't say anything..just walk away very slowly

    Hi mahgninnuc93,

    Did you use Tiny Umbrella to check which SHSH blobs are available?

    SHSH blobs are required to restore any non-current iOS (except 3GS 4.1).
    Download and run Tiny Umbrella (link below, post #1), advanced tab,
    ... check 'set Hosts to Cydia', Save SHSH, give it a min to finish;
    ... uncheck 'set Hosts to Cydia', Save SHSH, give it a min to finish.
    ... In the General tab, what SHSH blobs are displayed?

    While you're waiting, re-read post #1 Tiny Umbrella for valuable info.

    Since I purchased this phone on craigslist will there be SHSH blobs or is this something I would have to establish once I get it jailbroken and unlocked?

    One never knows what is available until you check. Please check as instructed.

    Something is wrong. Two (or more) should be found.

    With the General tab selected, in the lower-middle of the screen you should see:
    Device Model
    Installed Firmware Version
    Installed Baseband Version
    ECID (Dec): ECID (Hex)
    Serial Number
    IMEI:

    What is displayed for the first 3 lines?
    Send a PM with the ECID (Dec) and I will check also.

    Nothing is showing in any of the spaces. I will close it and re-open. How long should it be before anything shows in those spaces?

    Do you have the latest iTunes installed?
    Tiny Umbrella must recognize the iPhone before anything else can be done.

    From iTunes / Store, log-in or create an Apple account ..and.. 'Authorized This Computer'.

    Warning: When you plug in your phone later ...
    ... answer/press 'NO !!!' when iTunes asks to download or download and install anything !!!
    Never allow iTunes to automatically restore or upgrade the iPhone !!



    Do you have 4.2.1 SHSH blobs?

    Good. That eliminates one step. Currently, you're on stock Apple 4.2.1 firmware

    Download 4.2.1 iOS firmware .
    Download and run resdn0w 0.9.6rc18, select one option 'install Cydia',
    ...... pay attention, follow the count-down timer closely to enter pwnd-DFU mode
    Done with jailbreak.

    Run redsn0w again, select one option 'install ipad baseband' ....
    Done with bb update.

    Install ultrasn0w (via) cydia.
    For T-Mobile, turn OFF 3G settings/general/network
    Any SIM should work now.

    If not settings / general / reset / reset network settings

    You're welcome.

    @mahginnuc93. I checked you ECID and could NOT find SHSH blobs for 4.2.1.

    If you ever need or want to restore to 4.2.1, you can not ....
    ..... unless you use iFaith and create a 4.2.1 'pre-signed' firmware.
    ..... iFaith must be run while the phone is working
    ..... I suggest 'Do it Now'
