The iPhone 4G/HD has to be one of the most-leaked products in Apple history, and if what the people over at superiphone.cz have is real, then we've got yet another leak on our hands.  The site, based in the Czech Republic, claims to have put the iPhone HD's screen under a microscope to confirm the pixel density of the device.  According to the site, the screen is an IPS display similar to that on the iPad and the resolution is set at 960x640, quadrupling the number of pixels in the iPhone 3GS for easy upscaling of apps.  The current iPhone is starting to lag behind its predecessors in terms of displays, so we wouldn't be surprised if this rumor became real.  WWDC is a little over a week away, so it won't be long before all is finally revealed.
