Reports suggest Apple's iPhone 17 lineup will feature titanium casing on only one model, deviating from the Pro-exclusive approach of the iPhone 15 and 16. The specific model receiving the titanium upgrade remains undisclosed, making it an unexpected move. This shift could impact the perceived value and differentiation between iPhone models, potentially influencing consumer purchasing decisions. Apple has yet to confirm these reports. The move has stirred speculation about Apple's product strategy and design choices for its upcoming flagship devices.
