    I bought an iphone 3GS that was locked to o2, I wanted to put my 3 sim in there so I jail broke the phone and that worked fine. I then realised that I needed to flash the baseband to unlock the phone. I tried jail-breaking again whilst flashing to the iPad 6:15 baseband. This seemed to work fine but when the phone starts up it won't receive a signal at all, also when I go into settings and info about the phone the baseband box is completely empty. Is there anything I can do to save my iPhone? Any help would be greatly appreciated.

    Did you download iPad 1 3.2.2 onto your computer before you flash it? If not, that the reason you see it empty because redsn0w can't find it on your computer to install it onto your phone.

    No I did not install the iPad software (I really don't know enough about jail breaking to do it). What shall I do now to solve the problem, jailbreak again with the iPad software on my mac? Thanks for your quick reply

    Download Ipad 1 3.2.2 firmware onto your computer. Run Redsn0w again with Install Cydia & installing Ipad baseband check,

    You should be good to go.

    I've jail broken again and flashed to the iPad baseband but all I got was the connect to iTunes screen. I downloaded tinyumbrella but that wont kick it either I'm really at a loss as to what to do.

    4.3.3 which is what was on the phone originally, what should I have installed? Again thanks for your help and patience with this.

    Do you have 4.3.3 SHSH blob save for this phone? If not, you can't restore to that firmware because Apple is no longer signed this.

    Restore it to 4.1. For some reason, Apple is still signed this firmware.

    Ok thanks, I'm a bit confused as to what I've managed to do with the host files. They seem to be in my Documents folder and look like this which I'm sure isn't right.


    ##
    # Host Database
    #
    # localhost is used to configure the loopback interface
    # when the system is booting. Do not change this entry.
    ##
    127.0.0.1 localhost
    255.255.255.255 broadcasthost
    ::1 localhost
    fe80::1%lo0 localhost

    Edit: I've tried to restore and iTunes is giving me error 20

    Did you use the customs firmware or Apple official firmware? you need to use Apple official firmware.
