Hello all. I have a hacked iPhone currently at version 1.0.2 I would like to take it all the way to 1.1.2 but I have no idea how to carry out this procedure. Does anyone know a guide that will guide me step by step on unhacking my iPhone so I can upgrade to 1.1.1 and then to 1.1.2? BTW, is there a way to completely brick my iPhone in this process or do all brickings have a way to undo? Thanks!
