1.Do I need to buy a cable? If so, which one? All I have is the stock DCU-60/
2. Do I need to unlock all 4 locks or is the network lock sufficient?
3. I know nothing about drivers. Angelica wants good sound and a good camera. I have read that there are many upgrades. I understand that it is personal preference but I don't know enough to have a preference! What are good upgrades that most people use?
