Touch and hold an empty area on your Home screen.
Tap the Widgets tab > Direct dial.
Tap the contact in your Contacts list, then tap the Home screen.
You can change the look of each Direct dial widget for easy identification. Touch, hold, and release the Direct dial widget, then tap it. Select a theme icon or a photo icon, then tap OK.
