In iOS 6, when a message appeared on your lock screen, it
displayed the sender’s full name. However, iOS 7 changed that, and now a message only displays the
first name of the sender. That’s all fine and good (and much cleaner), but what
if you have a number of contacts with the same first name? Sure, you can usually
take the context of the message into consideration when trying to figure out
which John or Jennifer is texting you, but why have this added layer of
confusion? Instead, you can reclaim that last name in the lock screen with a simple change of a
setting. Here’s how.

  1. From
    your home screen, tap Settings | Mail, Contacts, Calendars
  2. Under
    Contacts, tap Short Name
  3. Tap
    the type of name listing you prefer (Figure A)

You can also completely turn off the Short Name feature to
have the full name of the sender. To do that, simply tap the Short Name on/off
switch until it’s in the off position. The system will also continue to use
Nicknames (when a nickname has been assigned to a contact). You can turn that
off in the same screen by tapping the Prefer Nicknames on/off switch until it’s in the
off position.

This setting doesn’t just apply to the lock screen — it’s
global. So, if you’d prefer using short names for other features, it’s
either all or none.

That’s it! You’ve officially rid your iOS 7 device of a new,
annoying feature to help you always know who, exactly, is sending you a
message.
