    Default Where is the baseband/modem flash located (was hybrid iphone??)

    Was curious, where is the modem firmware flash located?
    Is it on the comm board, or the logic board?

    I have a pre 1.1.1 phone that won't restore.

    Seeing lots of (oops) 1.1.1 phones selling now.
    People who accidentally upgraded them, etc.

    Thinking maybe it's possible to downgrade a 1.1.1 phone to 1.0.2, then use a 1.0.2 comm board?

    i dont think it will work, when u downgrade the modem version remains as the one at 1.1.1 even though your firmware is 1.0.2

    Yes, I know that the modem firmware isn't flashed.
    If the baseband firmware is located on the comm board though, wouldn't swapping a 1.02 comm board allow it to work?

    That's why I was asking about the hardware location of the modem firmware.

    Anybody know if the chip is on the logic board, or the comm board?

    commboards are expensive and I don't think many people really want to replace them . It would be easier to get a turbo sim it still works with 1.1.1 firmware and modem firmware

    Not really....I bought a broken iPhone for $50 (dropped).
    I can't get it to restore, but can communicate with it using iphoninterface, jailbreak, itunes, etc.

    If the comm board is still good, and I can buy a "bricked" 1.1.1 phone for cheap, I was just wondering if the swap would allow a downgraded phone to function again.

    Can anyone confirm the hardware location of the modem flash, comm board or logic board?
