A site from the Czech Republic stands up that he has in his possession a prototype iPhone 4G/HD like those presented by Gizmodo and a website from Vietnam, moreover he posted a picture in which they claim that the internal structure of the screen of the future iPhone 4G/HD seen through the lens of a microscope. Moreover, those who own that site say that analyzing the structure of the screen, they noticed that the future iPhone will have an IPS screen with a resolution of 960 x 640 pixels, a resolution very close to that of the iPad tablet.
If it were so, then the resolution of the new iPhone will be 4 times higher than that of the current iPhone 3GS, and this is not a very gratifying thing, nor is it plausible considering that the future iPhone could have a screen as large as the one on the iPhone 3G/3GS.
Until now, there is no confirmation that the respective pictures (which I will add as soon as the traffic on that site decreases and I will be able to access it) are really real or that the future iPhone will have this resolution, however it's a week until WWDC and we will definitely see what Apple has prepared for us.
UPDATE: Below are images of the Nexus One, iPod Touch and iPhone 3GS screen under the microscope.
