It's past time for Apple to shake up the iPhone's image once again, and it's currently believed that it will do so by releasing two variants of the iPhone 6: one at 4.7 inches, and the other a 5.5-inch phablet.
Before today we had yet to see any evidence of what resolution these two devices might be, but now it seems that they might have a 828 x 1472 resolution - or even a massive 1242 x 2208, significantly greater than existing iPhones' 640 x 1136 ratio.

Long story short, files for the iOS springboard - the home screen from which apps are launched - might betray a resolution that doesn't match up with past devices.
What are those extra pixels worth?
Despite its larger size, with this increased resolution the rumored 4.7-inch iPhone 6 would still be sharper than the 4-inch iPhone 5S.
And with that 828 x 1472 resolution the screen on even the 5.5-inch iPhone 6 would still surpass the 300 pixels-per-inch that Apple defines as a Retina display. Obviously the greater resolution - 1242 x 2208 - would far surpass that as well, so much so that it actually seems unlikely, though it's impossible to tell for sure at this time.
These larger 16:9 resolutions could also open up more screen real estate, according to 9 to 5's calculations, making room for Apple to potentially add more icons to each home screen.
Whether or not that happens may come down to a design decision on Apple's part, though you can bet your bottom dollar that decision has already been made, if the iPhone 6 is going to launch in September as expected.
