Sprint have switched to leases with an optional balloon payment; Verizon, T-Mobile and AT&T offer 0% finance plans with no final payment to own the device. Regardless, all the networks offer their customers a new device with no money up front and the same monthly payment as soon as their contract expires. It's good for retention, but it means that a lot of customers are largely oblivious to the actual cost of their phone.
