You can view and sort your contacts via four default contact data fields - Created, Modified, Email and Last mailed date.
Select Contacts from the navigation bar and then select the appropriate address book or the All contacts address book.
The contacts list is displayed with the various column headings for contact data fields.
The column headings mentioned above are sortable and can be clicked on in order to sort by that column.
By default, the contact list is sorted by the Last mailed date in descending order (from the most recent mailed date to the earliest). This is indicated by the small triangle pointing downwards next to the Last mailed date column heading.
To sort by Created, for instance, simply click on its column heading.
The date is automatically sorted in ascending order (as the small triangle indicates by pointing upwards).
To sort the list in descending order, simply click the Created column heading again.
The column heading triangle changes to point downwards, indicating that the sort is now in descending order.
