No, the MapKit API does not support any manipulation of the tiles. If you're interested in just a static grayscale map, you might be successful in taking a MKMapSnapshot and manipulate the image afterwards. This won't work for an interactive map, though.

You can also put a semi-transparent image view on top of the mapView. This won't allow you to completely decolorize the underlying mapView. However, you might achieve a similar effect. See the Metropolis Compass app for example.

You could hit the map title API at google and recolor the titles and load them as a overlay. It would be a little hacky.

I knew some guys that did this in Flash. Google is ok with it with permission:

Check out Cloudmade's alternative mapping toolkit : http://cloudmade.com/products/iphone-sdk

Edit:

You could maybe overload renderInContext and then repaint the screen somehow. It sounds a bit dangerous.
