Hi, I just upgraded my old iPhone 3s to the iPhone 4s. I love the new design, the way it works and how it is a major breakthrough from my old phone. Nevertheless, I just found out that Apple has done something with it as it no longer plays music through the usual music docks (ie Bose, Yamaha, Logitech, etc). I thought they were broken until I tried playing back my wife's IPhone 4s and it works just fine. The problem is that the phone charges alright but it won't play any music through the music player's speakers. The playback is only through the iPhone's own speaker. I'm really frustrated as it seems it is no longer a universal dock and my new IPhone will mean that all my prior players investments are useless. Is it something wrong with my iPhone or is it a new issue with the 4s model???
