Apple’s release of the retina mobile devices has ushered in a new age of digital graphics. Now all iPhone 4 and 4S models are built with the same physical screen size, yet using double the pixels. This means you’re looking at 326PPI instead of 163PPI(standard iPhone display).
Now this new hardware adjustment has also changed the display resolution to 640 x 960px. This has released a surge of iPhone 4/4S wallpapers you can download to your photos and set as home screen or lock backgrounds. I’ve collected 32 examples of beautiful retina wallpapers you can download and setup yourself.
