Yes. Your iPhone gives you a few customization options to control your contact list better. To access the controls follow the Settings>Contacts path like we did above. Then, you can choose to sort by first and last name. If you want to separate your contacts by genre (for example, personal contacts and work contacts), you will need to use the Group options we discussed above. Doing this can be complicated if you haven't organized your contacts in your email accounts. But, if you have a work email and a personal email, you can toggle between the two accounts using the Groups option.
