T-Mobile's approach when it comes to luring new customers continues to nab loads of users. This time around, the so-called UnCarrier is offering a year of unlimited data on its LTE network for customers that convince friends to make the switch from Sprint, AT&T or Verizon. And yes, the acquaintance that actually has to sign the papers gets the same 12-month deal. The limited-time offer takes aim at Sprint's recent efforts to lure customers from rival carriers with increased data allotments for families, and follows the yellow-hued network ending its quest to purchase T-Mobile earlier this month.
