Go to contact list where it shows the list of names.
Tap and hold the desired name.
A menu will appear with "Add shortcut to home" at the bottom. Choose that.
That contact will appear on you current page. You can then move the icon anywhere. It will be the icon from the contact list for that person. A picture if you have one.
When you tap that icon the contact will come up and you can choose the phone # to dial directly.
So, dialing with two taps.
Hope this helps.
