    Hi all.

    I used redsnow to upgrade two 2G iphones to 3.0.

    One of them now has no wifi.
    It has no wifi symbol on the springboard.
    If I go to settings->network, it will not pick up my wifi network.

    Under settings->general->network, it shows that it does have a MAC address. And it shows 'unavailable' under network.

    I have not tested it yet for edge connectivity.

    I googled this problem, and found an apple support page.
    I went through all the steps, but none worked: resetting the network, resetting all settings and wiping the phone, even replacing the firmware again.

    After googling around, I've reached the conclusion that this was a common problem with this update.

    Does anyone know if there is a solution to this ?

    I found one forum post somewhere that says that one fellow solved this by downgrading all the way to 1.1.4, then using iliberty+ with a wifi fix payload, and then upgrading again.

    Does anyone know why this would work ?
