Hello all. I'm new here and would love some advice. I'm a huge Apple fanatic, but I've been on the side of Blackberry instead of iPhone. Now I have the option of switching. The 2 features that are really holding me back from switching to the iPhone are voice dialing (like the blackberry where you don't have to launch an app, but just hit the call button and say a name), and "turn by turn" GPS (not google maps which I know quite well). What apps are available for this ........help convince me to switch to Apple!
