With iOS 7 you can now choose to display abbreviated names in apps like Mail and Messages, allowing you to fit more information on the screen.
This is particularly useful for dealing with messages with multiple parties, but can also help when working with longer names as well.
By default, iOS 7 will show the user’s full first name and last initial, or a user’s nickname if you’ve set one.
If you prefer to disable this, or use another form of abbreviation, this can be changed with a quick trip into Mail, Contacts, Calendars in the iOS Settings app, under the “Short Name” option.
