If you're on the T-Mobile network, the un-carrier is currently running its Black Friday promotion which can save you up to $1,000 on an iPhone 13, iPhone 13 Pro, iPhone 13 Pro Max, or iPhone 12 series purchase, and a free pair of AirPods (2nd-gen) to go along.
The catch? You need to purchase any of the iPhones under a Magenta MAX contract for 30 months, and trade in an eligible device (any Pro variant of the 11 and 12 series qualifies for the $1,000 off).
If you're not on the Magenta MAX plan, T-Mobile will still credit you with upwards of $500 with qualifying a trade-in and 30-month contract. Basically, if you're willing to remain loyal to T-Mobile, it'll reward you with a hefty discount.
