    Default stuck on emergency call screen with no info at all about the iphone

    hi,
    a friend of mine got an iphone 3gs (unlocked one) and it was working fine until he updated to latest firmware (i guess 4.3.5) then the phone got stuck in the emergency call screen ...
    i'm not able to know the baseband, not even sure if this is the firmware he installed and knows nothing about it, my question is
    is there anyway to downgrade it to any other version and then get pass the emergency call screen so i can unlock it with ultrasnow or any other tool ? or this phone is dead ?

    TinyUmbrella can tell you the baseband version even when you are stuck on this screen.

    It's not possible to downgrade the baseband on the 3GS at all.

    Redsn0w can tethered jailbreak and get past the "slide for emergency" screen, but the only unlock option you have is the iPad baseband / ultrasn0w (which can have some unfortunate side effects)

    i was able to get past the emergency screen by installing custom firmware 4.2.1 using redsn0w
    now it got 4.2.1 activated installed and bb 5.16.02
    so what should i do ? because it's not yet unlocked even after using ultrasn0w
    use the ipad bb method ? or upgrading to custom 4.3.3 (which i read somewhere that ultrasn0w support unlocking it with the bb 5.16.02), can this be done, or ultrasn0w doesnt support 5.16.02 ?
    and thanks very much for you help.

    the ONLY way you can unlock via ultrasn0w is with the iPad baseband method.

    Whatever you read about 4.3.3 and 5.16.02 working with ultrasn0w is very incorrect.

    In your country none of the carriers authorise official unlocking. So your only software based choice is ultrasnn0w/iPad baseband.
    I would still evaluate your other options - like selling your curent phone and buying a proper "officially unlocked" iPhone as the iPad baseband has some serious drawbacks and once you load it on your phone, it can never be undone/removed)
