Thread: Update OS on 3GS - lose unlock?

  1. #1
    Question Update OS on 3GS - lose unlock?
    Hello all, im new to these forums. Having some issues that I hope you can help with.

    I have a 3GS on OS 3.1.3
    I had not updated because my jailbreak was not updated and it did not matter until now.

    It is a Canadian device and I am living in Denmark, so I do require it to remain jailbroken and unlocked to be used (Until I upgrade to a better device that is! )

    I am fine with redoing a jailbreak on my own, but the unlock is what I am unfamiliar with.
    The original unlock was done in a shop, by someone I paid to do it, so I am not sure what sort of unlock was done. Is there a way to check for this?

    I am worried that if I should do an OS upgrade though iTunes, that it will remove my unlock as well as the jailbreak. Do anyone know if this is the case?

    Its gotten to the point where it can take well over a day to sync my phone and well, I just really should upgrade from 3.1.3 anyways.. =P

    Please let me know if I left out any needed information!
    Cheers!

    You can only restore to custom firmware to preserve your unlockable .

    Download Tiny umbrella , plug iPhone in and click save shsh.

    In adv tab, under request shsh from cydia, do a select : save shsh ,then deselect and save shsh again.
    Tell me what you have.

    Look under general tab for shsh blob.

    I have selected the request shsh from cydia, but the save shsh button does not allow me to press it.
    Tried to find a way to get it to do so, but dont want to do too much incase I start something I dont want to.

    Alright, you can restore to custom firmware of 4.1, go build one from Snowbreeze here Hotfile.com: One click file hosting: sn0wbreeze-v2.1.zip
    Put iPhone into pwned dfu and restore to this you build.
    Use expert mode whether to activate or not to, depends if u have the valid sim to activate

    i did get it sorted and saved the shsh but it says "cydia does not have your shsh for iphone 3gs 4.3.5 (8L1) there is no way for you to get them. sorry. you are just too late."

    only its all in caps and bolded and looks much scarier than that..
