Apple's first folding iPhone, iPhone Duo, goes on sale in stores today. If you're tempted, a few minutes of checking first can save you a headache later.

What happened: Apple says iPhone Duo arrived at Apple Store locations on Friday, October 23. You can buy it in stores, on apple.com or in the Apple Store app. It's available today in more than 70 countries and regions, including the U.S., and in 28 more countries and regions on October 30.

What this means for you: iPhone Duo opens like a small book. Closed, you use a 5.4-inch outer screen. Open, you get a 7.6-inch inner screen that Apple says is 50% larger than the iPhone 18 Pro Max's. It runs iOS 27 and is rated IP68 for water and dust. Apple's new Siri AI is rolling out as a beta, in English only.

Our read: It's a very different phone from the one you have now. If you can, hold one in a store before you decide.

For storage, ways to pay and who should wait, see our iPhone Duo buyer's guide.

What to do now

  • Try it in person first. Open and close it a few times, and check that the outer screen feels big enough for everyday texting.
  • Check the price and storage on Apple's own store page. Look on apple.com, not a reseller ad, for current prices and storage options (256GB up to 2TB).
  • Ask about trade-in. Apple says it offers trade-in credit for an eligible iPhone 13 or newer. Check what yours is worth before you go.
  • Back up your old phone first. Then use Quick Start to move your stuff. Keep both phones near each other, on Wi-Fi with Bluetooth on, and plugged in. You won't be able to use your old phone for several minutes.
  • Want help? Apple says store staff can help you set up and move your data, and it's running free "Say Hello to iPhone Duo" sessions at its stores.

We'll update this if Apple shares more about availability or software updates.
