Hey, just browsing the forums as i quite often do and saw your post.
I just Jailbroke my brothers 3gs running 4.2.1 with greenpois0n.
after a few seconds of the scrolling text the Iphone i got an error about no firmware upload after 6000ms giving up and the jailbreak just hung there.
I used the force boot to turn it back on and all was good but no jailbreak.
Ran it a second time and everything worked brilliant, any ideas what happened first time round?
