Hi Guys. I recently purchased an already jailbroken and unlocked iPhone 3g 8GB. I am assuming it was unlocked with Pwnage Tool because it the pineapple and Russian Steve Jogs boot/recovery logos (which I hate). I am trying to figure out if it is possible to change those logos back to the stock apple logos. It is running 3.1.2 and 05.11.07, so I don't want to lose that for the fear of losing the unlock. I attempted to use redsn0w to do this, and it seemed to be working, but after the pc onscreen instructions close, and it says that everything else is completed on the phone, my iPhone screen just stays black and shows no signs of updating or changing anything. Does anyone have any suggestions? By the way, if it matters, I am using a windows pc. Thanks in advance for any help.
