Best Buy is offering the Apple iPhone Duo with 256GB of storage in Star White for AT&T customers. The device carries a release date of October 23, 2026, and is sold by Best Buy. It features a thin, foldable design with the largest iPhone display ever.

The iPhone Duo includes a durable titanium frame and unique iOS experiences. Its camera system is a 48MP Dual Fusion setup on the rear. The phone is powered by the A20 Pro chip.

The largest display uses a nano-texture inner screen to reduce glare and is 50 percent larger than the iPhone 18 Pro Max. The A20 Pro chip is built for AI workloads and delivers up to 50 percent faster performance on its 6-core CPU and up to 2.1 times faster on its 7-core GPU compared to the iPhone 15 Pro.

A dual-battery system provides all-day power. It offers up to eight more hours of video playback than the iPhone 15 Pro’s 23 hours when using the inner display. The model is carrier locked to AT&T.
