Sprint gearing up to offer $60 / month unlimited calling plan?

Sprint is offering planning to introduce a $60 a month unlimited calling plan. "After yesterday's barrage of unlimited calling plans left us all terribly underwhelmed, it seems as if Sprint is hoping to emerge as the knight in shining armor by undercutting the oh-so-popular $99 price point. According to unspecified "analysts," the carrier is gearing up to "offer flat-rate calling plans at up to a 40-percent discount to its rivals," meaning that yappers could talk 'til their batteries died (and then some) for around $60 a month." The Engadget has the deets on this one.
