Rumors have been going around for some time that the upcoming iPhone 4G would sport a higher resolution display, possibly one with a 960 x 640 resolution. Now it seems that some folks over in the Czech Republic have managed to do some detective work, and put the iPhone 4G’s display under the microscope, figuring out its pixel density and display technology. The verdict? They claim that the display is an IPS panel, consistent with what the previous iPhones have been using, and will sport the 960 x 640 resolution that so many folks have been dreaming about, which would make it the highest pixel density seen on a phone. With WWDC just around the corner, looks like all our questions should be answered in a week’s time.
