Hi, I am getting ready to purchase an audio adapter for bb 8830. My questions is this: If I am listening to music through headphones, will I be alerted to incoming calls through the headphones, or will I have to actually be looking at the phone to see that I have a call coming in? Then, once I am aware that I have an incoming call, will I have to unplug my the adapter and my headphones from the phone in order use the phone, or can I just answer the call and use the phone as normal while still leaving my headphones plugged in?

I ask this because Seidio sells two different adapters, and the answer to this question will dictate which one I buy.
