If you've ever had to upgrade an iPhone months after launch, you've likely felt some anxiety: you need a new device right now, but you know you'll feel buyer's remorse when the next model shows up in September. T-Mobile thinks it can set your mind at ease, however. It's launching a promo that lets you swap the iPhone 6 for its successor while locking in the $15 per month JUMP On Demand lease price -- so long as you buy the existing handset by September 7th, you just have to trade it in to upgrade. You'll also get first dibs on the next iPhone if you order it from the carrier within the first two days of availability, so you shouldn't be waiting for days simply because you ordered a few minutes too late.
You're also getting a perk that applies whether or not you care for shiny new hardware. T-Mobile now includes Apple Music as part of its Music Freedom effort, letting you stream albums and playlists on the fledgling service as much as you like without denting your monthly data cap. It's not a surprising move (virtually every significant music provider is covered at this stage), but it'll definitely make life easier if you absolutely have to listen to some T Swift during your commute.
