Has anyone else experienced really strong interference from the iPhone 3G with surrounding speakers? I cannot have my iPhone anywhere near my computer speakers or even my clock radio or else the speakers make a loud buzzing noise. This even happened to me in my car! With the radio off. There is nothing I can do to stop it. At work, just having my phone in my bag, five feet away, makes my coworker's radio buzz. This is insane... I've never heard of something like this from a cell phone. Is there anything that can be done?
