Apple revealed iOS 17 at its 2023 Worldwide Developers Conference on Monday, detailing updates such as its new Check-In safety feature and Live Voicemail transcription.

However, not all iPhones will be able to take advantage of these new functions. Some of Apple's older phones are being left out of the great iOS 17 update, most likely because newer, more robust software requires newer, more robust hardware to run it.

There's a strong likelihood that you're in the clear if you purchased your iPhone within the last three or four years. But if you're still clinging to the same device you've had since before 2018, it's worth checking whether you're able to update it to iOS 17.

Here are all the iPhones that will be compatible with iOS 17:

• iPhone 14

• iPhone 14 Plus

• iPhone 14 Pro

• iPhone 14 Pro Max

• iPhone 13

• iPhone 13 mini

• iPhone 13 Pro

• iPhone 13 Pro Max

• iPhone 12

• iPhone 12 mini

• iPhone 12 Pro

• iPhone 12 Pro Max

• iPhone 11

• iPhone SE (2nd generation or later)

How do I know which iPhone model I have?

If you haven't thought about your iPhone's model since you bought it, it's easy enough to check. Simply open "Settings," tap "General," then tap "About" to see your phone's Model Name and which version of iOS it's currently running.
