    Default 3gs 4.2.1 06.15.00 ->invalid sim
    hi!

    i'm using the 3gs with the 4.2.1 version and the ipad basement (06.15.00).
    i did the unlock and jailbreak a few months ago with redsnow and everything worked fine. today i did a few cydia updates and all of the sudden it says "invalid sim" and i have no network anymore.
    i thougt it would be because of the ultrasnow update i did and removed it completely, but that was not the reason.

    can someone help me please?

    Reinstalling Ultrasn0w and rebooting didn't solve the problem for me.
