What is the non-retina/retina resolution of iPhone5 in pixels. (Double or half of 640px x 1136px screen size)?
640px x 1136px
Is the retina 640px x 1136px or is that the non-retina?
1136px x 640px is the resolution of the iphone 5 retina screen.
So for example the default start up image for apps is called Defaultfirstname.lastname@example.org and is at 1136px x 640px
So I guess if you wanted a lower resolution it would be half that 568px x 320px but I would not recommend this.
