    I’ve updated the firmware to 4.3.3 and downloaded the corresponding ipsw, however the redsnow program won’t recognise the ipsw. I’ve downloaded it again and it still doesn’t work and it works with my 4.3.1 ipsw. I did use the downloaded ipsw as my upgrade/restore though, would that effect it?

    First you need to download the firmware and then use Redsn0w. Go to setting and check out your firmware from there. I think you are using 4.3.1 firmware, you haven’t followed the procedure properly.

    i keep getting an error about DFU mode….and i’ve tried it on more than one computer

    To enter into DFU mode you have to follow the instructions as it is. A slight delay will lead to an error.
