Verizon has "Friends and Family", T-Mobile has "myFaves" and now AT&T has the "A-List with Rollover" (not to be confused with the A-Team). 

AT&T customers with individual Nation plans of $59.99 or higher can phone up their very own VIP cast without tapping into their monthly allotment of minutes.  For individual plans, you'll be able to select up to five domestic phone numbers (mobile or landline) to call for free, while FamilyTalk customers with plans of $89.99 or more can select up to ten numbers.

According to David Christopher, Chief Marketing Officer for AT&T, “This is an incredible value for many of our customers that essentially lets them ‘double dip'.  Not only will they not use minutes from their monthly plan when they call their A-List numbers, but our unique Rollover feature means they can keep those minutes for use in future months." (Has anybody actually ever dipped into those rollover minutes?)

As with competing plans, AT&T users will be able to manage their A-List online through their MyWireless Account and change them anytime, allowing 24 hours for new numbers to register. 

A-List with Rollover premieres with AT&T on September 20, 2009.  The full  release on this new feature can be found over at AT&T's Newsroom.
