Here is a video I made this morning of the 3g buzzing. Its so loud the video picks it up in the background. This is my second iphone 4S. I am trying my luck again today at apple store. I really believe all of the phones have it but there is a degree of how bad this sound is. my youtube video (please be sure to increase your volume) : http://www.youtube.com/watch?v=L3Vg7NNQ1zk&feature=youtube_gdata_player apple forums about this issue and how even with replacements the issue is not fixed : https://discussions.apple.com/thread/3393647 Everyone, please listen to your phone is a very quiet environment over 3g (no wifi) and run something like google maps to 3g is collecting data.
