Starting today, longtime customers of T-Mobile (22 months+) are being offered an unlimited voice plan just for $50 a month. Finally, something for enduring that long 3G wait!

The plan, which originally kicked off in San Francisco, offers unlimited minutes for $49.99/month on a single line or unlimited minutes for $89.99/month on a two-line family plan. With add-ons, such as unlimited data ($24.99), and unlimited messaging ($9.99), you can get unlimited everything for only $85—not too shabby. [Boy Genius Report]
