Hi Pedro,
There are several ways to do it, but you probably want to do it when you
create the overlay. If you are not using the overlayItem tag for
anything else, just set the tag to the Geopoint, and then you can access
it by casting the tag to a Geopoint after you get the item in the code
below. As I said, there are lots of other ways.. but that is normally my
preferred way, because it keeps the information you want with the item.

Is there anyway to get the values that created this overlay and
compare them with the values of GeoPoint geo ? My code is
aproximmating values so I never get the numbers right... I don't know
which values can I use from the onTap method to compare with the ones
that created the overlay itself besides the latitude and longitude
values...
protected boolean onTap(int i) {
OverlayItem item=getItem(i);
GeoPoint geo=item.getPoint();
Point pt=map.getProjection().toPixels(geo, null);
View view=panel.getView();
((TextView)view.findViewById(R.id.latitude))
.setText(String.valueOf(geo.getLatitudeE6()/1000000.0));
((TextView)view.findViewById(R.id.longitude))
.setText(String.valueOf(geo.getLongitudeE6()/1000000.0));
((TextView)view.findViewById(R.id.x))
.setText(String.valueOf(pt.x));
((TextView)view.findViewById(R.id.y))
.setText(String.valueOf(pt.y));
panel.show(pt.y*2>map.getHeight());
return(true);
}

Any news on how to implement this ? Is overriding the class that
extends itemizedOverlay on the onTap method enough?
I need to show information when the user clicks a marker and cant seem
to find possibilities
Here are examples of how I've done it:
