It's funny you bring this up, because I'm having a similar problem. I just got a new phone (Samsung e105), and I bought the data cable so that I could manage and back up its phone book. The software supplied with the data cable will show the phone numbers on the screen and let me edit them, but when I try to export to CSV, it exports a blank file. I just found it very ironic that the primary purpose of having the data cable and software is the thing that malfunctions. The third-party Futuredial software works, but it only exports the phone book to its own proprietary file format, so I can't do anything useful with the file. Sigh.
