    i dont think you need ipad firmware if you using Redsn0w for windows, but you'll need your iphone ipsw either 4.1 or 4.2.1 whatever u got on your device

    Better solution update 4.1 then jailbrek and unlock (4.2.1 need redsn0w reboot every time you reboot your device confirmed by me I did it and don't like it)be carful your baseband will go 06.15.00 and there is no come back with baseband witch mean until apple relise base band higher then above(there is no confirmation thet normal update via iTunes will work)PS: I did it work's fine
