Hey all, Since my first cell phone I've always experienced cellular noise interference when my phone came close to any speaker system (this includes the original iPhone I had for the past 2 and a half years). Now, with my iPhone 4, I no longer experience any interference at all! I can finally take showers blasting my music from my iSound speakers without having to turn on Airplane mode. I'm assuming Apple knows this considering that I'm no longer prompted with an option to turn on Airplane mode when I dock the iPhone into the speakers, only a message recommending me to. First, HURRAH! Second, how is this possible? Why hasn't Apple toted this remarkable advancement in the phone's communication system? Anyone else noticing this?
