    Default iphone updating

    newbie sorry if this sounds like a stupid question.

    i do have cydia & ultrasnow 1.2.3 installed.

    ok Itune wants meto update to just says 4.2.

    if I do update will I lose my ultrasnow unlock or is ultrasnow 1.2.3 an unlock for version 4.2 ?

    Do not let iTunes update you to 4.2! You will lose your unlock.

    You must use a custom ipsw to load 4.2.1. Pwnagetool on the Mac will build one for you.

    See the sticky thread about 'how to check if you can unlock' for details
