A lot of companies are coming out of the woodwork with their iPhone 4Gs (or at least that's what their claim is, but it's nothing we can confirm at this point). Now, someone has put it under a microscope and compared the screen to that of the iPhone 3Gs, the iPod Touch and Google's Nexus One.
If these finding are to be believed, the screen will be quite an upgrade from the previous models. The front will be a 960 x 640 IPS display. Which, according to Engadget, is four times the pixel count of the iPhone 3Gs.
