Mine is definetely from the wireless. When it's on and loading something I can see it, when it's off there is no interference.
On a side note, how do I get the facebook app to show my wall and stuff. I saw the thread on it, but there is no real solution. I tried uninstalling the app in fb, restarting my zune, etc but no luck. I still only have two permissions in fb for the app.
