For checking whether phone number exists or not, you can do like,

ABMultiValueRef phoneNumberProperty = ABRecordCopyValue(person, kABPersonPhoneProperty);
NSArray* phoneNumbers = (NSArray*)ABMultiValueCopyArrayOfAllValues(phoneNumberProperty); 
if([phoneNumbers count] > 0)
{
    // more than one phone numbers exist
}

And for email,

ABMultiValueRef emailprperty = ABRecordCopyValue(person, kABPersonEmailProperty);
NSArray* emails = (NSArray*)ABMultiValueCopyArrayOfAllValues(emailprperty);

if([emails count] > 0)
{
    // email exists
} 

Hope this helps you…
