Does anyone know why the iPhone4 is so noisy in nearby audio gear? I've been a long time AT&T customer and have owned several GSM phones and none of them were as noisy as the iPhone. If I have my phone within 2 feet of my computer or speakerphone I get a constant Bzzz...bzzz...bzzz of GSM noise. With prior GSM phones I only had a bit of GSM interference when the phone was about to receive a call (made for a nice early warning system). Otherwise they were pretty much silent. The iPhone chatters away even when asleep. To have a little peace and quiet I need to put the iPhone on the other side of them room.
