Deviceseeker:Sources have confirmed that the new iPhone is going to feature a 4-inch touchscreen at a resolution of 1136 x 640 that will eventually lead to a pixel density of 326ppi. This means that the iPhone will have the biggest pixel density in the 4-inch category, though analysts say that this fact is irrelevant because there aren’t too many smartphones with a 4-inch display.
