This thing hasn’t been out for more a week, and already Palm and Sprint have issued an update that enables a significant new feature. A new page over at the Palm support site has just gone live, noting the availability of a new patch that brings full voice dialing over Bluetooth support to Palm’s new king of the hill Treo 800w. Oddly absent from the first shipment of handsets, it’s still good to see both Palm and Sprint taking a proactive approach to delivering new features to their customers. Then again, both of these companies need all the help they can get to retain subscribers and users respectively, so any little bit might be too little too late.
