MKMapView broken in 3.2.3 / OS4 - Can't set region

Question

In the last version of Xcode, set region worked fine, now in 3.2.3 it doesn't snap to your specified region?

After View did load...

 [mapView setMapType:MKMapTypeHybrid];
 [mapView setZoomEnabled:YES];
 [mapView setScrollEnabled:YES];

 MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } };
 region.center.latitude = 41.902245099708516;
 region.center.longitude = 12.457906007766724;
 region.span.longitudeDelta = 0.04f;
 region.span.latitudeDelta = 0.04f; 
 [mapView setRegion:region animated:YES];

 [mapView setDelegate:self];

This is the code that worked fine, now it doesn't snap to the location denoted above, it just shows the world map.

Any help greatly appreciated.

I've done it lots in 3.2.3 and iOS4. I promise it works.

I like MKCoordinateRegionMakeWithDistance().

CLLocationCoordinate2d coord = { 41.902245099708516, 12.457906007766724 };
MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(coord, 1000, 1000);
[mapView setRegion:[mapView regionThatFits:region] animated:YES];

That "1000, 1000" in the second and third arg are the latitudinal and longitudinal meters of the range component of the region. Passing the region through the mapview's -regionThatFits: method is just good practice.
