Just paired my old S9 with my iphone. Sound is very good, but only the volume and Play/Pause buttons work.
Why can't I use the Advance button?

Will apple include the AVRCP in a later release?
I've found a trick to get past the lag with motorola s9s- if u have lag, hit te Bluetooth icon and change to speaker, then switch back again to the headset -it seems to jog the Bluetooth into syncing! Works for me anyway!
