I wanted to see if this sounds like a good deal. T-mobile just started a new Jump On-Demand where you can lease an iPhone 6 for only $15 a month & No money down for those with good credit. Just pay $15 a month and you can simply turn in the phone at any time and upgrade (with a new lease plan obviously) up to 3x a year. Sounds like a good plan for those that like to have the latest device at all times?
