Did you purchase your current iPhone 6 for $15 per month through T-Mobile's JUMP! On Demand trade-in program? If so, you'll be automatically eligible for a free upgrade to Apple's 'iPhone 6s'—or whatever it will be called when it's released this fall.
In addition to permitting its Simple Choice customers to listen to their favorite songs on Apple Music without taking a byte of their monthly 4G LTE data, carrier T-Mobile today announced that iPhone customers participating in said upgrade plan will be able to get their hands on Apple's next-gen handset without paying anything to upgrade or increasing their monthly JUMP! On Demand payment.
