According to a report from FierceWireless, Sprint Wireless is reversing course and is once again offering two-year service contracts to its customers. The company stopped offering contracts just this January following similar moves by other tier-1 carriers over the last few years. However, as of Friday, the Sprint website now offers customers four options in total: leasing a handset, buying it outright, paying for it in installments or once again signing a 2-year deal.
