The problem is that requires perfect foresight!  It is way friendlier
to make it easy to find stuff in hindsight.

You can use the aggregatedisplay widget that is used for the wallpaper
and ringtones.  Each section could be a week/month/year as appropriate.
The items can be a simple icon (red X for delete, green plus for add
etc) and text ("Deleted Joe Bloggs", "Modified Jane Doe").  You can use
code from the phonebook merge thingy to show how an entry changed if
you want to show detail (eg on a double click).

Some calendar type control hooked into the phonebook tab.  Usually
it is set to "current", but if you change it to Jan 1 2003 then you
see the phonebook as it was then.
