My A900 works perfectly in PCS Power Vision mode through a USB connection. I get amazing speeds (up to 1.5mbits) and the icon on the phone indicates that it's using the Power Vision connection.
However, when I connect through my Bluetooth dongle, it only uses PCS Vision at around 200kbits.. and the icon on the phone indicates it as such.
I hope this make sense.
Anything I'm doing wrong?
