Place an annotation at a random point in a mapkit

I downloaded the source files from this blog:
iPhone SDK 3.0 – Playing with Map Kit – Part 3 - ObjectGraph Blog

I would like to change the part where the code shows your current location, just to add an annotation a random place I've found.

I added a image sight in the center of the main view, so it's possible to see where the annotation will be dropped.

But how do I find the coordinates of the sighted?


Thanks in advance

In Apple's own Maps app, they got a button "Place the pin" and it drop a pin in the center of the map.

Its that part im looking for. Anyone know how I get the coordinates so I can drop the pin?
