Yahoo MUST allow the contact list to sorted by last name. I know of no list of names that cannot be sorted by last name, nor do I know of any list that appears in order by first name. It appears that Yahoo combined the contact list first name and last name into one name, not separately as first name and last name, as was the case before. Having a list of names listed only by first name is virtually unusable.
