I'm awaiting delivery of my 770. I have a bit of time to create a wish list and it includes number display when paired to a mobile. I have a Jabra headset with number display, and figure that it couldn't be all that difficult to implement on the 770 (assuming it hasn't been already). Imagine, the 770 sitting on its stand, on your desk. Your mobile rings and walla! The caller's number is displayed onscreen.
