So, I have a friend who I talk to on the phone quite often. She has an AT&T 3G phone... not an iPhone... some other phone. It's like a RAZR or something... but keep in mind that it's 3G. When I used to talk to her on my old iPhone, in the middle of our conversation I'd randomly hear this loud screech. It sounded almost like someone screaming bloody murder, but it was clearly some kind of electrical interference or glitch of some kind... Well, ever since I got my iPhone 3G, people have been telling me that they hear it from my phone now! I don't hear a thing... but the person on the other end will randomly be like, "What was that?!?" Has anyone else experienced this? It sounds to me like an AT&T 3G issue over an iPhone issue since it happens on other 3G phones... Maybe it's something with 3G in my area?
