Apple iOS 6 Update Indicates New iPhone Will Have 640 x 1136 Display

Posted Aug 7, 2012

iOS 6 now is able to scale to show five full lines of apps when displayed at a 640×1136 resolution.  This indicates that the upcoming iPhone 5 will have a 4-inch screen.  The current version of iOS 5.1 can only show four apps when running the same iOS simulator app.  There would not really be a need to support an additional row unless the screen was going to get bigger.  We’ll find out officially in September though.
