well i frequently get a no accessory message everytime. It repeatedly keeps on saying This accessory is not optimized for this iPhone. I do not know why it keeps on popping the message every time. Also one more thing that I have noticed in the iPhone is that there is no audio from iTunes or there is no audio from the bottom speakers as well. I have never plugged into any accessory till now then also it is giving such type of strange error. Well I want some quick solutions for this type of problem. Please do reply as early as possible.
