I have been lurking here for sometime now and I think I am ready to JB. One question I need answered is how do I first make a back up of my phone in case I need to restore it? I just sync'd my ipod 3g and saw it was making a back up when it was done sync'ing but where did it put this back up. If I need to restore do I just restore and then install my back up?? Do I have to make a clean back up first of is this sync'd back up all I need? Also, when I JB do I still keep all my app's I have purchased??
