if its anything like the k800i then all you do is place the cable in to your fone and then in to the pc, i then have to select fone mode on the actual fone. then Sony place a icon on my desktop called " Sony Ericsson File Manager" open that and then treat it as a normal folder, drag and drop the files on the the fone, in the folder you want them stored, you can use real player to rip cds to mp3 that you already own. or if you dont want to buy the cd then you can download a p2p program such as limewire and download songs
