How to change label of a contact field with only the keyboard

I can confirm after testing that these fields are not available on the iPhone 4 in iOS5, although they are available on the iPhone 4S.

However, if you have your contacts synced with Address Book on the Mac, you can add the field to the contact card via the Add Field menu item under Contact, and the field is then sent to your iPhone on the next sync. I am not able to confirm if you can do this via the iCloud web interface directly.

It is possible to assign multiple twitter ids to a contact. You have 2 ways of achieving this. Through iOS or through the Address Book app on Mac OS.

On iOS 5 you can add multiple Twitter accounts to a contact on the device like this:

• Chose a contact
• Edit
• Add field ...
• Select Twitter
• Enter the twitter account

When you already have a Twitter account field you can't add another one like this anymore. Instead you will have to do as follow:

• Under the Twitter field you will see an empty field for Facebook, LinkedIn, Myspace or Flickr
• select this empty field's name and chose Twitter
• Enter the additional Twitter account

You can repeat this procedure for additional accounts.

This doesn't seem very intuitive at first, but it looks like Twitter, Facebook, LinkedIn, Myspace and Flickr are simply subcategories for a dedicated "social network" field and are managed just like other multiple entries fields on the device:

• email -> work, home...
• url -> home page, home, work, other...
• date -> anniversary, other

On Mac OS using the Address Book Application. Select the contact you want to edit, edit it.

• To to the menu Card -> Add Field -> Twitter ...
• And add the twitter account.

Repeat as many times as needed.

Your contacts will sync shortly afterward.
