I have a jb Ipod touch, and use it in my car all the time. I just have some random tape deck adapter.... I got the 3g and have been using it in my car ( love pandora!!! ) but i get what sounds like feedback through the speakers. Sometimes its crazy loud. When I put the earphone adapter even close to the phone it will give feedback. I drive an audi with the bose system so i dont think its that, i use my ipod Touch and no issues.... So whats with it?? It seems like the phone is interfering some how....not all the time, but I wanted to know if anyone has seen or heard of this.... Should I try another adapter? Also, when at work I cant keep my Iphone next to my desk phone...it creates a static noise in my work phone... And from what I can tell its only when I have to use Edge...3g doesnt seem to give same problems... Is this interference?? Radiation? Am I getting cancer? Really I just want my iphone to play music correctly in my car...and FM transmitters suck Thoughts??
