    Last week i lost everything, IEMI, ICCID, MAC Address, etc.

    I did the folowing:

    1) Downgrade BL to 3.9 with ziphone 2.4.
    2) Restore my phone to version 1.1.1.
    3) Ran the baseband downgrader to downgrade the baseband to 1.1.1.
    4) Restore iphone to 1.1.3 with itunes.
    5) Activate and jailbreake with ziphone 2.4.
    6) Unlock with anySIM 1.3

    After that, anything came back to normal and i ended with a fully functional iphone on fw 1.1.3.

    Hope this helps.

    i have tried to downgrade bootloader but no success. I think currently the modem firmware is lastest (4.03.13_G) with BL 4.06. I don't if this is the main trouble that I couldn't downgrade BL. How about your modem firmware?
