Where can i find greenpois0n and how to i do that? I will take your advice and wait for the unlock.. I will just jailbreak it to be "prepered" for the unlock.. So the jailbreak step by step will be the same guide as the iClarified, but just to change the ipsw download ? I bought the phone in France so the carrier is Orange. I think i have all under control now except the greenpois0n guide... Thanks in advance

yes, same procedure for redsn0w, just use the right IPSW.

iClarified - iPhone - How to Jailbreak Your iPhone 3GS, iPhone 4 Using Greenpois0n (Windows)

Thanks! I managed to jailbreak the phone without any problems.. I used just greenpois0n.
After I jailbroke it, I have now 2 strange files on my desktop. "iBSS.n88ap" and "kernelcache.release.n88". Can I delete them? Or will that be a big mistake? And If so, can I just make a newfile map to put all the greenpois0n things..?
And will I be using greenpois0n again? Can I delete that too?
I now that Cydia is great and all, but the only reason why I have this is for the unlocking.. So I hope I can earase it after the unlock if its possible..
Now that I have done this, will I be needing the pwnage map whick contains the ipsw and redsnow?

I will now just wait for an unlock.. So the best updates will come in Devblog i guess..
