I just got this speaker dock for my ipod. Its great, except lately my ipod has been getting very hot in a very short time (like 10 mnutes) of just having the ipod in the dock. I have used other docks (with speakers) and have noticed the same things, except the dock i have now hasnt been giving me problems until like a week ago. What could be causing this? I have left it in the dock overnight before, and it didnt get nearly as hot. Is there anything i can do to prevent this? i still want to use the dock.
