This might be a silly question, but it's getting to the stage where it's just plain stupid. I ran out of space again, so was clearing some room. My iPad is saying that I have 3.2GB free. But iTunes is saying I have 5.28GB free. I get that there is a bit of a difference between the two sometimes, but that's two GB that seems to be unaccounted for according to iTunes. I have no idea what is going on, but I've tried everything to get them to agree. Nothing works!! Any ideas??
