I was trying to jailbreak my new verizon iphone with OS 4.2.6 on my mac with Greenpoison. I followed the instructions on how to put it in DFU mode and it was in the process of jailbreaking until Greenpoision crashed. I was able to restore my iphone but i am now afraid of attempting again lol...any reason as to why greenpoison crashed in the middle of jailbreaking?
