After revamping its pre-paid offerings last week, Cingular Wireless today debuted retooled post-paid plans. Designed to be more simple, analysts also believe that the new plans could also increase revenue since the cheapest plan is now $39.99 monthly (up from ($29.99). There are now four featured plans, all include Rollover:

• Nation 450 - $39.99
• Nation 900 - $59.99
• Nation 500 FamilyTalk - $59.99
• Nation 1500 FamilyTalk - $99.99

In total there are 12 plans–it appears regional plans have been discontinued across the board. Per minute pricing stayed the same for low-end plans, is slightly higher for mid-grade plans and is cheaper for high-end plans.
