Hi, I am thinking about Jailbreaking my iPhone 4. I already downloaded the Greenpoison jailbreak and tried it on my iPod Touch, worked like a charm. I am hesitant on my iPhone because I rely on it so much for work. Anyway, I was told that after you jailbreak it you have to re-register or re-set it up it through itunes. Is this right? Can someone please tell me what happens after you jailbreak your phone? I mean, can I just jailbreak it and use it like normal (make a call, etc..). Thanks for any advice.
