    Default No SIM card works after downgrading from 1.1.3 to 1.1.1.
    What do i do to make the SIM cards work? I tried to downgrade with iTunes and it came up with the error, so, i looked if it was downgraded, and it looks just like a 1.1.1 ready for activating. It booted up after the error and looks fine. All wrong is the SIM card prob! heres the video tutorial I used:

    umm, more details bro. what firmware were you at before u upgraded to 1.1.3?

    did u do a full 1.1.3 upgrade or the nate soft 1.1.3 update?

    were u at 1.1.2 before u went up then back down?

    1.1.1 firmware will not work with any newer baseband modem firmware.
