I'm rounding up all the best Apple iPhone Duo preorders in the US and UK — here's how to save as much as possible

The highly anticipated Apple iPhone Duo has officially opened up preorders after a lengthy wait. The device, Apple's first foldable smartphone, is set to launch on October 23rd at a price of $1,999 / £1,999. Preorders are available through Apple's own stores and website, as well as through major carriers such as Verizon, T-Mobile, and AT&T, in addition to UK networks O2, Vodafone, and EE.

To secure the best possible deal on the iPhone Duo, there are several promotions and discounts to consider. Trade-in rebates of up to $1,200 are available across all carriers, making it crucial to assess eligibility for the maximum discount. Furthermore, carriers like Verizon, AT&T, and T-Mobile are offering enticing deals on the iPhone Duo when bundled with a new line and unlimited data plan.

For example, Verizon's "Simplicity" plan allows customers to bundle the iPhone Duo with an unlimited data plan for just $72/mo, with an additional $30/mo saving due to additional device credit. AT&T offers up to $1,200 off with a trade-in and new line, while T-Mobile provides up to $1,000 off with a trade-in and new line on their Experience Beyond plan.

Xfinity Mobile also offers a $1,000 discount for trade-ins and a starting price of $15/mo for new customers on an unlimited plan.
