My Dad's friend asked me to unlock his 1G iphone yesterday to get 2.0 on it and unlocked. So I used PWNAGE tool, and got it unlocked. It worked perfectly when I gave it to him, unlocked, jailbroken, perfect. Today, he emailed me saying: "[M]y iphone went black, flashing and now I have a white screen. I didn't update or did anything with it. I am not sure of why the phone would act as such." I asked him to try putting into DFU mode and seeing if iTunes would detect it, but I have yet to receive a response. Is something wrong????
