Just got a new iPhone4 5.0.1. Downloaded the latest redsnow and extracted it. I had troubled it seemed getting into DFU mode, but I think I was in it everytime , but I didnt know it. It gave me a black screen that was hard to get out of. Redsnow says it is undetected, but it does detected it when I accidently put it in recovery mode. Is this a common problem????
