iphone 4.2.1 got upgraded to 4.3.1
i used redsn0w to jailbreak it and it has cydia, but i can't get to unlock to other carriers.
i tried downgrading it, but keeping getting the error 3194, so i changed the host, but still doesn't work.
was anyone successful in downgrading the iphone or getting the 4.3.1 unlocked?
I have strong opinions about things that don't matter.
