// In the future, if we wish to get this "positioning" correct,
// we'll need to do the following:
// 1. Change the layout to in the cursor adapter to:
// android.R.layout.simple_list_item_checked
// 2. replace the selection / focus code with:
// getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
// getListView().setItemChecked(mInitialSelection, true);
// Since the positioning is really only useful for the dialer's
// SpecialCharSequence case (dialing '2#' to get to the 2nd
// contact for instance), it doesn't make sense to mess with
// the usability of the activity just for this case.
// These artifacts include:
// 1. UI artifacts (checkbox and highlight at the same time)
// 2. Allowing the user to edit / create new SIM contacts when
// the user is simply trying to retrieve a number into the d
// dialer.
