I just received my Nokia Hands Free Kit from the mail, and this afternoon I went to shop for components for the installation according to the FAQ instruction. When I ask for a RJ-45 cable from a local computer store, the sale-person asked me if I need straight-through or cross-over. I checked the FAQ, and it doesn't say anything about what type of cable should be used. I have no knowledge about Ethernet so I don't know the difference between the two. Could someone tell me which cable should I used? Thanks in advance.
