Assuming you're with Yahoo---

Open your address book---scroll to the bottom of the page and you will see these links---

';sort by';-------First--Last--Email.

Click on ';Last'; and the A-book will be re-arranged---Last Name first--(alphabetically by default)Change address book from First to Last?
