yeah, unfortunately apple did not synchronize UINavigationController's animations. Andrew's solution is excellent, but if you don't want to cover its whole functionality, there is a simpler solution, override these two methods :

// navigation end event

- ( void )  navigationController    : ( UINavigationController* ) pNavigationController 
            didShowViewController   : ( UIViewController*       ) pController 
            animated                : ( BOOL                    ) pAnimated
{

    if ( [ waitingList count ] > 0 ) [ waitingList removeObjectAtIndex : 0 ];
    if ( [ waitingList count ] > 0 ) [ super pushViewController : [ waitingList objectAtIndex : 0 ] animated : YES ];

}


- ( void )  pushViewController  : ( UIViewController* ) pController 
            animated            : ( BOOL ) pAnimated
{

    [ waitingList addObject : pController ];
    if ( [ waitingList count ] == 1 ) [ super pushViewController : [ waitingList objectAtIndex : 0 ] animated : YES ];

}

and create an NSMutableArray instance variable called waitingList, and you are done.
