Hi all Hope some can help me and my Iphone. I have a 2G, and did JB it now, first time. With redsn0w. It was all ok, then I was done and going to unlock it. Then the screen turns black, it freezes with the apple logo flashing now and then. When I hold the on/off and home button in, it turns off. When I turn it on, the same screen comes back.......ai ai ai. What to do??????
