How do I switch first/last name order in the iOS address book? My contacts are arranged by last name first in my iPad and iPhone and I want to have them first name then last name. Where do I access the address book preferences?
Go to Settings.
Scroll down and click the Mail, Contacts, and Calenders preference. 
Now, scroll until you are under Contacts heading. 
Select the Sort Order option.
Choose which way you want to sort your contacts.
