Below the Mail section will be Contacts options. The two main iPhone Contacts Settings that you will have here will be Sort Order and Display Order. These just correlate to how the names in your Contacts will be either sorted or displayed.
The Sort Order arranges them by last name and then first name. This means that if you want to find someone in your iPhone Contacts list you will look by last name. This can be switched so that it is first and then last. The Display Order decides how they will be seen, which is set as first then last. This means that even thought they are sorted by last name they will be listed first then last. Below that is a button to Import SIM Contacts, and this requires a SIM card with the appropriate contacts.
