  • Sushrut says:

    Hi.. I bought my iphone 3gs last year from ebay.. I was told it wasn’t jailbroken (which of course was not true). I used it in South Africa, it worked fine. Took it back to India, it worked fine with an Airtel sim.. I think i might have updated the software in india(i really dont remember)..

    But then once back to SA, it did now work on a S African sim, it just goes to a weird mode, can see a connecting chord and itunes symbol and emergency calling mode (basically network locked)..
    I tried to restore the initial software using itunes(BIIGGG mistake). Now it does not recognize any network or sim, back to the weird mode..

    PLEASE HELP!!! I am not understanding the technicality of this damn phone!!!!

    If you have done all the above and still have problems with your network (Like I did) take your sim card out and put it back in, stupid I know but worked for me!

    Good luck!

  • Naga says:

    A Real big thanks to dev team. I could unlock the IPHONE with these simple steps. I thought i have to spend atleast Rs500 to rs1000 for unlocking but with easy steps i could do so.

    For people who still facing the problem 3gs (7e18) 5.12.01

    Please download spiritjb.com to jailbreak your phone.
    Download spiritjb to your desktop
    connect your iphone to the system.
    run the spiritjb application.

    Wait till the process completes.
    Now Cydia is installed.

    open cydia. will ask to upgrade packages choose complete packages.

    go to Manage section
    3. Now click on sources and click on edit to add following repo
    Repo666.ultrasn0w.com (it’s ‘0(zero)’ and not ‘o’)
    4. Now search for Ultrasn0w 0.93 and click on install
    It will do the rest. Insert the other carrier sim and you can see the left top right the name of provider. its cool ryt!!!

    For people who’s WIFI is gone. Don’t get panicky. :-)

    Just Goto Settings–>General–>Reset–>Reset All Settings(If you have entered any code it will ask please enter the code)

    your WIFI will be back.

    Hi,

    I am bringing my iphone 3gs unlocked from canada, it is on version 4.0. I am wondering if it will work on the airtel network in delhi. Also, to get a prepaid data plan on it would i just purchase a sim card and add the money on to it then.

    Thanks for all your help.
