The idea of a smaller iPad has been rattling around the tech rumor mill for many a month now, but the iPhone's 3.5-inch screen? That's sacred surely? Well, according to the Wall Street Journal, apparently not. It's reporting that those ever-famous "people familiar with the situation" have told it that Apple has ordered screens that are larger that the ones used in the flagship phone so far. There's no specifics on size, with the sources only going as far to say they are "at least" four inches. Apple, however, has declined to comment -- no surprises there -- but perhaps now is the time to start the office pool. Just hope you don't land on the "4-inch iPad" square.
