Last year I bought my wife a Cambridge 700something table radio....it's a nice radio almost a Bose (no flame please). Whenever I get near it with my Captivate it (the radio, not the phone) buzzes. The Radio is off, but off with the remote so maybe not really off, but asleep. In another room in the house there is a powered sub-woofer for the regular component stereo. The woofer does the same thing....buzzes when the Captivate is nearby. I have seen 2 other ATT phones do the same thing, but my old verizon phones never did. I sometimes notice interference if my Captivate is near my Panasonic desk phone at work, and sometimes it makes my radar detector in the car go nuts....laser alerts & K band alerts as well. I'm so concerned that I've been wearing a tin foil hat (again). Anyone have any thoughts on this? If your going to ask about the hat, its one of those 3 cornered colonial looking ones, very patriotic & stylish too.
