    Talking 3G 2.2.1 with modem firmware 01.48.02

    Hi
    My friend updated my 3g to 2.2 in December but the modem firmware was left 01.48.02. Now I've updated and jailbreak to 2.2.1 and the modem firmware is exactly the same, 01.48.02. How can I upgrade my modem firmware? I also need to unlock.
    Thanks in advance

    Just restore to the standard FW 2.20 - this will update your BB to 2.28.00 so you can use YellowSn0w.

    Not weird at all, he used a custom FW and preserved the BB.
    Restoring the standard FW 2.20 (not 2.21) will upgrade the BB to 2.28.00 and enable YellowSn0w to work.
