Amidst the flurry of iPhone 6 rumors coming from KGI Securities' report last week, Ming-Chi Kuo presented the first possible screen resolution for Apple's 4.7" iPhone 6. Kuo lists it as a 1334x750 Retina display with a pixel density of 326 pixels per inch. Historically, Apple has been very cautious with resolution changes in their iOS devices. The original iPhone was launched with a 320x480 resolution. Eventually, Apple moved to 640x960 Retina display, doubling the linear resolution in each dimension. That allowed existing apps to simply be pixel-doubled to fill the entire screen. Developers could then take their time to update their apps to fully support the higher resolution display. When Apple moved from 3.5" to 4" screens in the iPhone 5, they simply added vertical resolution. This allowed existing apps to run in a letterboxed format with black bars at the top and bottom of the screen.
