I have some custom tiles that I have created that overlay nicely in google maps. These tiles are 256x256 png's. I looked at the ExtendedMapField example and it's pretty much what I want to do. Which is take a .png and draw it over blackberry maps. However, I'm struggling with the blackberry maps coordinate projection. For google maps there are 256 x 256 tiles where the number of tiles are 4^n. Does any one know the format of the blackberry maps tiles?
