Upcoming iOS 6 is scalable to taller, 640 x 1136 iPhone display, shows possible next-generation device user-interface
Mockup of rumored next-generation iPhone design — With the next-generation iPhone's announcement and release approaching for next month, one of the most present rumors is a larger, nearly-four inch display.
Context & Ripple Effects
The taller-display rumor has been building all year: in March, AppleInsider reported claims of a 4.6-inch Retina Display for the next iPhone, which John Gruber's Daring Fireball pushed back on, and back in July 2011 9to5Mac's leaked silicone cases already pointed to a thinner, tapered body. What is new today is the software angle — a mockup showing iOS 6 itself scaling to a 640 x 1136 canvas rather than another accessory or supply-chain leak.
That matters because an OS build adapting to a taller aspect ratio is harder to dismiss than case molds, and it lands weeks before the device's expected announcement next month. The story traveled unusually wide for a mockup, picked up same-day by MacRumors, TechCrunch, Wired, AllThingsD, Macworld and others — a sign the market is treating display size as the open question of this cycle.
First-order effects
- If the 640 x 1136 panel ships, every iOS developer faces a letterboxed-or-rebuilt decision on launch day, since existing apps are built to the current 3:2 aspect ratio and Apple's SDK transition becomes the immediate work item.
- Case and dock accessory makers who bet on current iPhone dimensions face another redesign cycle, repeating the pattern their 2011 tapered-case orders foreshadowed.
Second-order effects
- Android handset makers, who have already normalized screens well past four inches, lose 'bigger screen' as a differentiator if Apple moves, forcing competition onto other axes like software services and camera.
- App publishers gain a fresh reason to prioritize iOS updates over other platforms, since a resolution change concentrates rework spend on whichever store owns the upgraded installed base.
Third-order effects
- Apple's long-standing single-aspect-ratio discipline — one resolution for the whole ecosystem since 2007 — would give way to a cadence of periodic layout breaks, making display transitions a recurring tax on the developer base rather than a one-time event.
- A confirmed move would also validate the leak-driven news cycle as a pricing signal: carriers and retailers could pre-position inventory and marketing around rumored dimensions before Apple says a word.
The trend: Smartphone displays are ratcheting upward under competitive pressure from larger-screen Android devices, with Apple's rumored shift marking the moment the last holdout against bigger screens joins the curve.
