The third way of entering a Fast Dial is to press the Services button on your phone;
then select Fast Dials; scroll to the number that you want to set a Fast Dial for and press
the softkey button below Assign. You can then enter a phone number that you want to
assign to that Fast Dial. Note that when using this method, you can just assign a phone
number to the Fast Dial and cannot tie it to the Personal Address Book.
