Apple's iPhone Duo foldable phone will open for preorders tomorrow, October 16th, at 8am ET / 5am PT, the company's product page confirms. Customers who want the device can begin preparing their orders now rather than waiting for the preorder window to begin. The early setup option lets buyers select the color they want, along with storage capacity, carrier preference, and whether they want to arrange a trade.

The trade option is offered as a way to make the $1,999 foldable a little cheaper, according to the product page. Once a customer enters all of those details, the only step remaining tomorrow morning will be to confirm the order.

Customers who complete the early setup process will find the iPhone Duo sitting in their cart ready for checkout once preorders open. Apple's system gives shoppers a way to save time and move ahead of people who are still customizing their iPhone Duo details when the window begins.

There is a lot of hype surrounding the iPhone Duo, and the early cart system should give Apple a good sense of how many customers are willing to put down money before preorders officially open. That signal arrives ahead of the October 16th start time, when the company will learn how much demand exists at the moment ordering begins.

For anyone who waits until tomorrow rather than preparing a cart in advance, The Verge has said preorder details will be available on its site at 8am ET sharp. The iPhone Duo is Apple's foldable phone, and its $1,999 price puts it at the top of the company's lineup.

The preorder arrangement covers the color, storage capacity, carrier preference, and trade-in choices that customers would otherwise make after the window opens. Buyers who set those details now will only need to confirm tomorrow morning.

Apple has not said how many customers are expected to use the early setup option before preorders open. The product page for the iPhone Duo is where the selections can be made ahead of the October 16th start.
