It appears Sprint's answer to T-Mobile's UnCarrier campaign hasn't been quite the success the company hoped it would be. Less than four months after it announced its "One Up" early upgrade plan, Big Yellow began phasing out the tariff from January 9th and is now directing online customers to its new "Framily" plan instead.

The One Up plan, however, was specifically designed to reduce the cost of upgrading to a brand-new smartphone every year. While Sprint has axed its One Up plan, it is providing a couple of similar alternatives. The first, called Sprint Easy Pay, allows customers to buy a device for a smaller down payment and then pay off the rest of the device over 24 monthly installments. Read the full story at Engadget.
