True contacts application taken from Android source is the stock most recent ICS contacts app. If you want to taste real Android try this true contacts applicaton. Manufacturers replace Android apps with false apps - e.g. Samsung - so it is not even possible to add all contacts numbers. This build is ad-hoc demonstration of true Android.
I removed dialer in this build.
True contacts are good for Local Sync and all apps that create contacts accounts (see http://www.psencik.cz/local-sync/local-sync-and-android-4-ics) because manufacturer's Android 1 apps are lacking features of Android 4.
