So, for example, whether you want to distinguish amidst a contact’s home and vacation home phone numbers, you might want to label one of the fields “Vacation.” Here’s how you do that:

Choose a contact from your contacts menu and hit the “Edit” button in the top right corner. I created one, and now I want to delete it. Not a problem.

Readers Rob and Katy have a question for us:

When you edit a contact’s phone number or newsletter address, you have the ability to “Add Custom Label”. First, a little background. While you’re in that screen that lists all the labels, just tap the “Edit” button in the top right hand corner and you’ll see the little red minus signs seem next to each label, just as whether you were deleting emails or text messages.

The iPhone’s contact management system is very similar to OS X’s Address Book. whether you don’t like what the iPhone’s picked for you, tap the label to go to the full list of labels (both included and custom).

So what whether, like Rob, you want to get rid of a label? Under each section of contact knowledge (Phone, newsletter, web page, address, etc.) you’ll see an “Add new…” option, marked by a green plus button.

Select the type of info you wish to add—say, a new phone number— and enter the number.

All the way at the bottom of the list you’ll find “Add Custom Label.” Tap that and you can enter and save any label you want. How?

Excellent question, guys. Below that will be the label that the number will be assigned. Tap the minus sign and hit delete for the label you want to get rid of and you’re all set. As in Address Book, the iPhone lets you add custom labels to any notes field.
