Review: Samsung Infuse 4G
The calling and contacts applications on the Infuse are the same basic calling and contact applications that are found on most Android devices. They receive the same splash-of-color treatment that the Droid Charge did. The functionality of this app is unchanged, however.
The Infuse does include the Samsung "Buddies Now" home screen widget that can be populated with links to up to nine buddies. It loads up a full-screen carousel with the faces of your nine top friends. Scroll through the list for easy access to calling and messaging tasks via the action bubbles that appear in the widget next to your friends' avatars.

If you want to look at a buddy's entire contact card, simply press their avatar and you'll be taken into the contact application. This app can be used instead of setting a handful of contact shortcuts to the home screen.
