    Hi,

    I've been using iPhone without jailbreak for 1 year ( iPhone with polish ORANGE's SIM lock ), however now I'm studying in London and I need to use english SIM card. Yesterday I made jailbreak to my iPhone. Before I made Jailbreak I updated my software in Itunes to 3.1.2 . Everything went great ( I made it with pwngtool 3.1.4 ) but unfortunately I still can't use english sim card because phone is blocked. I heard that 3.1.2 can't be unlocked, but I'm really fresh in that things and I don't know what to do :( Maybe should I downgrade software to 3.0, unlock it with cydia's ultrasn0w, and then do an update? If yes, please tell me how can I make it. I'm really stupid in these things, PLEASE GIVE ME HELP :( NOW I'M PAYING A LOT OF MANY FOR USING POLISH CAREER IN UK, I CAN'T AFFORD ON IT :( please give me step by step

    regards, a lot of thanks,
    M.

    I believe that once your baseband(which allows for unlocking) is updated, there's absolutely no way of downgrading it.

    Even when someone will publish 3.0 custom ipsw file? Do someone think that's a chance that ONE DAY ( i mean close future ) will someone publish software to unlock new baseband from sim lock?

    Ok, but unfortunately I think i've updated my baseband ( with 3.1.2 update from itunes before jailbreak ). It means that ANYTHING can help me? Can I install back old baseband? What another I can do to take off that SIM lock? Please help me

    Sadly, I don't know of anything you can do.

    The only thing I can think of to try is to ask Orange in Poland if they will unlock it officially for you, given the situation. I know Orange in France do that, but I don't know about Poland. It's worth a try.

    If you have Cydia, install Fuzzyband and run it to see if you might have bootloader 5.08. That is the only chance to downgrade your baseband.

    About 10% of the early 3G phones had this baseband. If you have 5.09, there is no unlock for the foreseeable future.
