i'm about to jailbreak 4.1 now using the greenpois0n on mac os. when i plug my ip4 the itunes pop up and sync goes on. the question is do i need to eject my ip4 before jailbreaking or just leave the itunes and iphone hooked up?
I've heard of other people getting confused by a message in greenpois0n that looks like it means the JB has failed, but it really isn't, and they just have to wait and let the process finish. So try again, and just wait it out. Or just try limera1n, it doesn't throw out such confusing messages.
