Apple is gearing up for its highly anticipated iPhone 17 launch, and as the excitement builds, it's safe to assume that the tech giant will discontinue these four iPhone models. With Apple's track record of discontinuing older models to make way for the new, it's likely that these devices will no longer be available after the iPhone 17 event concludes. So, if you're an Apple enthusiast or simply looking to upgrade your smartphone, now might be the time to make that move before these models become a thing of the past.
