As the iPhone 17 series progresses towards the final stages before entering mass production, newly surfaced dummy models offer a detailed glimpse into significant anticipated changes for Apple's next smartphone lineup. Revealed in a hands-on video by AppleTrack, these physical mock-ups showcase substantial evolutions in design and product strategy compared to previous generations.

One of the most notable shifts is a revision of the product portfolio. The established 'Plus' model appears to be discontinued, making way for the introduction of a new 'Air' designation. Consequently, the expected iPhone 17 lineup consists of four distinct models: the iPhone 17 Air, iPhone 17, iPhone 17 Pro, and iPhone 17 Pro Max.

Across these four devices, three different design philosophies are evident based on the models shown. The iPhone 17 Pro and iPhone 17 Pro Max are depicted with an identical aesthetic, dominated by a large, horizontal camera matrix module that occupies the entire width of the device's upper section. The sheer size and configuration of this rear camera assembly have led to online commentary humorously comparing its appearance to the Xiaomi 11 Ultra.

The newly introduced iPhone 17 Air stands out as a particularly unique offering. While its rear design features what appears to be a standard, elongated camera module shape, the device truly distinguishes itself when viewed from the side. It is positioned as potentially the thinnest iPhone ever produced; the dummy model measures approximately 5.59mm in thickness, giving it a profile roughly half that of the corresponding Pro models.

However, achieving such an ultra-slim form factor seems to involve specific design trade-offs. The mock-up indicates that the USB-C port is not vertically centered along the bottom edge. Furthermore, accompanying reports suggest potential compromises internally, including a battery capacity rumored to be only slightly above 3000 mAh. A more significant rumored change is the complete elimination of the physical SIM card slot for this model.

This potential move to an eSIM-only configuration for the iPhone 17 Air introduces uncertainty regarding its availability and implementation in key international markets, particularly mainland China. Questions arise whether this signals a push towards broader eSIM adoption in the region, if Apple will produce a market-specific variant retaining the physical SIM tray, or if this specific model might not be offered in China. The final approach remains speculative at this stage.
