iPhone to have 960×640 double-resolution display? (Updated)

John Gruber took the opportunity of the Wall Street Journal‘s post today on the Verizon iPhone to tout his sometimes obvious, but also new tidbits of information.  While the WSJ talked about a Verizon iPhone, Gruber segues to the general iPhone 4G which he says will have a front-facing camera (no kidding!), an Apple chip (like they’d go back to Samsung now?), and third party multi-tasking (which was pulled from 3.x at the last moments).  

He also mentions that the screen will be 960×640, which is double the current resolution (double height, double width).  While its pretty obvious that Jobs would get laughed off the stage if he tried to release another 320×480 iPhone
