“For the sake of argument let’s take it as a given that the next iPhone will sport an 1136 × 640 display, with the same 326 pixels-per-inch resolution as the iPhone 4 and 4S, the same width, but an extra 176 pixels in height, changing the aspect ratio from 3:2 to 16:9,” John Gruber, who is by no means convinced the rumor is real, writes for Daring Fireball.

“Let’s further assume that this new iPhone will not be announced until later this year, say, around October, just like the 4S last year,” Gruber writes. “How might Apple get developers on the right track to support a new aspect ratio at WWDC next month while maintaining their standard radio silence regarding as-yet-unannounced products?”

Gruber writes, “The easiest way: By doing nothing at all. iOS 6 could be announced next month without Apple saying a word about supporting multiple aspect ratios. Then they could just announce the new iPhone in October and expect developers to get on board ASAP. Apple says ‘Jump’; iOS developers ask ‘How high?’ But, keep in mind, iPhone apps are already expected to be at least somewhat flexible in height.”
