The iPhones that get iOS 26 (the latest iOS version, as of 2025) are all models from iPhone 11 and newer, essentially any iPhone with the A13 Bionic chip or better. This includes:
- iPhone 11, 11 Pro, 11 Pro Max
- iPhone 12, 12 mini, 12 Pro, 12 Pro Max
- iPhone 13, 13 mini, 13 Pro, 13 Pro Max
- iPhone 14, 14 Plus, 14 Pro, 14 Pro Max
- iPhone 15, 15 Plus, 15 Pro, 15 Pro Max
- iPhone 16 series (various models)
- iPhone 17 series (various models)
- iPhone SE (2nd generation and later)
Older models like iPhone XS, XS Max, and XR are not supported for iOS 26 and will remain on iOS 18 for security updates.
If the question was instead about iPhone OS 2 (the original iPhone operating system version 2 from 2008), it was supported on the original iPhone and the iPhone 3G, with several software updates during its lifecycle. But currently, all modern iPhones run much newer versions starting from iOS 18 up to iOS 26.
Please confirm if the question is about the historic iOS 2 or recent iOS version 26.
