iPhone Duo preorders open Oct. 16: dates and prices to know

Apple's first foldable iPhone has a lot of people talking, and the key dates are close. According to MacRumors, preorders for the iPhone Duo open Friday, October 16, at 5 a.m. Pacific, and the phone goes on sale Friday, October 23, in the U.S. and more than 70 other countries. Another 28 regions get it on October 30.

It is expensive. The iPhone Duo starts at $1,999 with 256GB of storage. The 512GB model is $2,199, 1TB is $2,599 and 2TB is $3,199. It comes in two colors, Star White and Night Sky.

AppleInsider reports that starting October 12, Apple will let you prepare your order ahead of time by choosing your color, storage, carrier, AppleCare+ plan, shipping and billing details, and payment method. That can save time on preorder morning, which matters because AppleInsider also mentions reports of limited supply.

If you are not sure it is worth the price, waiting a few weeks is a reasonable choice. Reviews from people who use the phone day to day will answer questions about the hinge, the battery and durability that a launch event cannot.

Before October 16, look up what your current phone is worth as a trade-in and decide which storage size you would really use, so the decision is made before the clock starts.
