How can I programmatically launch Contacts.app on the iPhone

Question

I would like to launch the Contacts.app when the user needs to add a contact. My app already reads from the contact API. I would rather not re-implement functionality if I can avoid it. I am targeting iOS 4.0 and above.

If you want to add a contact, use ABNewPersonViewController. See Interacting Using UI Controllers for full details on this and the other AB UIViewControllers.
