Editing the Contacts List
Remember that there are four ways to dial: Favorites, Recents, Contacts, and
Keypad.

The Contacts list is the source from which all other lists spring. That’s probably
why it’s listed twice: once with its own button on the Home screen, and again
at the bottom of the Phone application.
Contacts is your address book—your master phone book. Every cellphone
has a Contacts list, of course, but the beauty of the iPhone is that you don’t
have to type in the phone numbers one at a time. Instead, the iPhone sucks
in the entire phone book from your Mac or PC or MobileMe
Actually, it can slurp in your phone list from the SIM card of an older GSM
cellphone,
It’s infinitely easier to edit your address book on the computer, where you
have an actual keyboard and mouse. The iPhone also makes it very easy to
add someone’s contact information when they call, email, or send a text message
to your phone, thanks to a prominent Add to Contacts button.
But if, in a pinch, on the road, at gunpoint, you have to add, edit, or remove a
contact manually, here’s how to do it.
➊ On the Contacts screen, tap the ± button. You arrive at the New
Contact screen, which teems with empty boxes.
Many computer address book programs, including Mac OS X’s Address Book, let
you place your contacts into groups—subsets like Book Club or Fantasy League
Guys. You can’t create or delete groups on the iPhone, but at least the groups from your Mac or PC get synced over to the iPhone. To see them, tap Groups at the top of the Contacts list.

If you do use the Groups feature, remember to tap the group name you want (or tap All Contacts) before you create a new contact. That’s how you put someone into an existing group.

Ordinarily, the Contacts list sorts names alphabetically, either by first name or last
name . There’s no way to sort it by company name...or is there?
Yes, there is. When you’re creating a contact, tap the First Last box—but enter only
a company name (in the Company box). Then save the entry. If you bother to go
all the way back to Contacts, you’ll see that the entry is now alphabetized by the
company name.
You can now reopen it for editing and add the person’s name and other
information. The entry will remain in the list, identified (and sorted) by company
name.
➌ Type the person’s name. for a refresher on using the
iPhone’s keyboard. Tap each field (First, Last, Company) before typing into
it. The iPhone capitalizes the first letter of each name for you.
If you know that somebody has AT&T like you, add “(AT&T)” after the last name.
That way, when he calls, you’ll know that the call is free (like all AT&T-to-AT&T calls).
