I just picked up a Blueant S4 handsfree. So far the unit works much better than I expected, so pretty happy with it.
Works well with the iPhone 3GS and also the Bionic.

HOWEVER, I am unable to get the Bionic's STOCK App or VLINGO app to recite back received text messages or allow me to dictate and send text messages hands free.

Has anyone have any experience with any combination of the above to get text messages to be read out when arrived or dictate to send via voice without having to interact(use hands) with the Bionic?
