If you are asking about Google Map in iPhone SDK 3.0 then you need to look at MKCoordinateRegion and MKCoordinateSpan in MapKit framework.

You can set the co-ordinates of your map view by setting MKCoordinateRegion and zoom level by using latitudeDelta and longitudeDelta property of MKCoordinateSpan.

for example,

   CLLocationCoordinate2D location;

   location.latitude=yourlatitude;
   location.longitude=yourlongitude;

   span.latitudeDelta=0.01;  //or whatever zoom level
   span.longitudeDelta=0.01;

   region.span=span;
   region.center=location;

   [mapview setRegion:region animated:TRUE];
   [mapview regionThatFits:region];

Hope that helps...
