    I have the same problem (also on first Gen) while trying to downgrade back, get error code [20] have tried to go back with 8.1 and 8.2 neither work (on Win XP)

    Wish now I had read a bit more into it as I was under the impression we were good to go, but now see we can't unlock till Friday it seems? (info on 3.0 around here sure is scattered and confusing of late) I NEED my phone and can't wait till Friday so I hope someone can help.

    If you have gone back to iTunes 8.1 or lower, you should be able to put phone in DFU mode and then restore. Worth a try.

    Dose not work... get same error code with 8.2 or 8.1

    ok so error code [20] is in restore mode only.

    However still get an error in DFU mode as well now showing [1600}

    Dose anyone have any actual knowledge/experience with this that can help in detail?

    I am reading that a custom ipsw may solve the code [1600]? so dl'ing now, will try that in a few and update if there is a change.

    I upgraded to the 3.0 release earlier and I was stuck at the same emergency call screen.

    iTunes 8.2 wouldn't let me downgrade

    I used my sister's computer which has iTunes 8.0.2 on it and I put it in DFU Mode, and restored to 2.2 (I didn't have 2.2.1 file) and it worked without error

    So i followed some other ideas on this problem and removed all apple/itunes files from my pc, installed itunes 7.4 and tried restore again. Now i get error code 5 and sometimes error code 1 and still can not downgrade my phone! been working on this all day and night now! (its 4am)


    Also clarified some things. I was good to go in updating to 3.0 with the exception that my phone was jailbroken/unlocked with quickpwn and not pwnagetool so my activation got screwed! (stupid pc garbage! *misses my power book*) Now after all this fawking around with it, my phone is restored to factory with 3.0 and stuck there with still no real help or answers.

    On top of it all I have not heard nor read anything yet about a windows version for unlocking/jail breaking 3.0

    FINALLY! got it fixed and unlocking with quickpwn as I type this.

    Used itunes 7.7 after removing all traces of apple from Win XP
    SIM removed
    Used non custom 2.2 firmware (custom firmware showed error 1602)
    phone in DFU mode (restore mode has error code 20)
