The program lets customers try out Sprint's plan without the constraints of a contract. New customers need to sign up at their Sprint store or online to buy or lease a new phone. Customers who signed up before April 5 get Sprint's earlier refund, which lasted for 14 days.

"We're putting our money where our mouth is," Roger Solé, Sprint's chief marketing officer, said in a press release Friday.
