Sprint has announced a new offer for those who want to pick up the iPhone 6s or iPhone 6s Plus to compete against T-Mobile. The US carrier will let you walk away with the new iPhone from just $1 per month. For a limited time only, and starting this Friday morning at Sprint stores, you'll be able to take advantage of the new offer, which is part of Sprint's iPhone Forever program.

The $1 a month is for the 16GB iPhone 6s, while the iPhone 6s Plus will start at $5 per month, when you trade-in an iPhone 6. The company will also take iPhone 5s units, but this will add an extra $9 to each option, meaning you'll pay $10 for the iPhone 6s per month, or $14 for the iPhone 6s Plus. Higher memory configurations will cost slightly more.

It's an interesting offer and one we're sure many will look into this coming weekend. As a reminder, through December 31 of this year, Sprint will also offer anyone who switches from another carrier, or happen to be an existing customer with an eligible upgrade, a promotion of $15 per month for the iPhone 6s 16GB, which is usually $22 a month without a trade-in.

Your move, T-Mobile.

OVERLAND PARK, Kan. (BUSINESS WIRE), September 24, 2015 - Sprint has the world's best offer for iPhone fans who can't wait to get their hands on the iPhone 6s and iPhone 6s Plus.
