I read on LifeHacker that you had to change a GV setting to show the GV # when taking a call. But I've left it on showing whatever # is calling, theoretically since GV is the middleman between calls it shouldn't matter. But anyone test it themselves? The problem with setting the GV setting to showing the GV # all the time is you have no idea who is calling you unless you leave presentation settings on and then it will tell you their # or name (if they followed directions) after you answer the phone.
