Address Book Framework and POP, IMAP, or ActiveSync Contacts
<p>Can the <code>ABPeoplePickerNavigationController</code> be called to display Contacts from a  different account than the default?  For example, a gmail, or Exchange account?  I've read the <code>ABAddressBook</code> documentation and all I find is code below to the default Address Book on the iphone.</p>

<pre><code>ABAddressBookRef addressBook = ABAddressBookCreate();
</code></pre>
