T-Mobile was already offering one of the best deals on a new iPhone 6s or 6s Plus for $20 per month through its Jump on Demand program, but it looks like the company is ratcheting that up. The magenta carrier's CEO, John Legere, just took to Twitter to announce that this Friday, customers will be able to trade up to an iPhone 6s for as little as $5 per month. From Legere:

Legere notes that the monthly price depends on which model you're trading up to, and what model you're coming from, but customers will end up paying between $5 and $15 a month after everything is said and done. Customers who have already pre-ordered with a trade-in can also take advantage of the offer. Details of the deal are limited to a series of tweets at the moment, but Legere says more info will be available soon.
