using greenpois0n to jaibrake my iphone4 it starts jailbraking then when the iphone boots to a black screen with the writing on it hard to make it all out think it says
unable to find gbdevist,
unable to find re-mount,
unable to find re-unmount,
unable to find re-load-file
greenpois0n initialized
After you click jailbreak greenpois0n will upload the jailbreak to your phone. Eventually all the code will run on the iphone screen. And then reboot with apple logo morphing into the greenpois0n logo. Does greenpois0n say its finished at any point on your computer screen?
