#1)  When I connect the SDA to my PC via USB, I loose WIFI abilitys.
Is this normal?  I use the USB to charge while browsing and don't have
the 110v charger where I am.

#2)  When listening to MP3's I can press the button on the H500 and I
can listen to the MP3 for a few seconds on the H500 earpiece.  But this
is just asking for a voice dial and then a cuts off.  How can I get the
H500 to listen to MP3's fulltime?  I realize the battery will die
quickly, but that is fine.  

Thanks;

Edwin
