IPhone Duo pre-order starts Friday, October 16 — $1,999 base price, AT&T offers up to $1,200 off with trade-in. Apple’s first foldable hits stores October 23. No Indian pricing or launch details confirmed yet.  The iPhone Duo was announced alongside the iPhone 18 Pro and iPhone 18 Pro Max at Apple’s 'Surprise and Shine' event, but unlike those models, it won’t ship until late October.  Pre-orders open globally at 5:00 p.m. Pacific Time on Friday, October 16 via apple.com and major carriers. AT&T is the only U.S. Carrier so far to announce concrete savings: up to $1,200 off with an eligible trade-in, $800 toward an existing device balance for switchers, and $200 per line for online orders. Xfinity previously announced preorder deals, but no specifics were shared in this reporting.  At $1,999, the iPhone Duo undercuts the Samsung Galaxy Z Fold 8 by $100. Though both sit well above the $1,599 Galaxy Z Fold 7 launched last year. That gap matters most for buyers comparing foldables across ecosystems, not just price tags.  No Indian pricing, launch date, or carrier partnerships have been disclosed. Apple has not confirmed whether the Duo will be available through Flipkart, Amazon India, or local retail partners, nor whether it will carry the same $1,999 starting point converted to rupees.  IOS 26 compatibility is implied. But the source does not say whether older iPhones like the 13 Mini will lose support or see performance regressions. That’s a separate issue, covered elsewhere.  Pre-orders go live Friday. Shipments begin Friday, October 23.
