On my old phone I could set up freq. called #'s with a speed dial # i.e. if I dial # 3 it would call one of my kids.
How do I set thatup on the Droid?
This might not be the solution you're looking for, but you can add frequent contacts to your "Favorites". Then when you go into phone mode, click "Favorites" on the top and they'll be in there.
