    you must go downgrade itunes to 7.5 and have your iphone in DFU mode, though i highly suggest staying with 2.1 for it is far better then 1.1.x firmwares and just work out the problem

    Try this. Go to Settings->General->Reset->Reset network Settings. If this doesn't work out, you may want to give a try to "Reset all settings".

    If that doesnt work do a DFU restore to a stock FW 2.1. Make sure your using the latest itunes.

    If that doesn't work try this. I found it on another forum. It looks like it fixed it for most people.

    1. downgrade from 2.0 to 1.4
    2. unlock with iliberty, check off just the six boxes on 1st page
    3. restore with itunes
    4. unlock with ziphone, check fix wifi then do it all
    5. restore with itunes
    6. unlock with iliberty but this time check off all six and go to advanced, click third tab and get all the payloads, but make sure you check off these ones, 1.dev team grey wifi fix and 2. fix no sig, no wifi, no bt 3. i checked off others like bsd subsystem, and open ssh but the rest shouldnt matter, as long as you have the first 2. then hit go for it all on iliberty and once its done you should have wifi!!

    7. restore to a stock 2.1 (DFU) then pwn and restore to a custom 2.1.

    From what I read about error 20 the only thing that seems to fix it is a DFU restore NOT recovery. The screen must be black.

    DFU Mode for 2.0: Plug into iTunes...Power phone off... hold power + Home for EXACTLY 10 seconds... release power but continue to hold home (screen will be black)... and within 20 seconds iTunes will recognize it.

    restore to a stock 2.1

    If you still get no wifi read and use this...
    http://wikee.iphwn.org/sgold_bootrom:fixwifi

    You may need to be on 1.1.4 for it to work so AFTER you DFU restore to 2.1, DFU restore back to 1.1.4 and there should be no reason to downgrade itunes as long as you are actually in DFU mode.

    And never ever use ziphony again!
