Hi, i'm new on the forums, i was wondering a couple things. I own an ipod nano 4gb i think its 3rd generation. It's the square shaped one with video on it. Anyway, the music is almost filled up on that and I was really thinking about getting a 32Gb 3rd gen. touch, but when i do, and open it and plug it in what will happen. Will my library get deleted or all put onto it. I want to be able to start from scratch and put different songs onto the touch.
