Most cell phones will make monitors buzz, but every once in a while when my iPhone 4 is on my desk (in the same place as the iPhone 3GS), my monitor buzzes much louder than any other iPhone ever made it do. It's a very audible buzz. Has anybody else noticed this? It concerns me a little that it's making my monitor buzz so loudly, possibly indicating the iPhone 4 should be used in a case and not have the antenna exposed. The volume that previous iPhone's made my Samsung monitor buzz at never really bothered me, but the iPhone 4 is making it buzz pretty loudly. I knew this wouldn't do anything to my monitor in the past, but this is much louder, and it's concerning me a little.
