Parsing information to scenes

Hi there,. I am a game designer, and admittedly a very basic programmer. I am wondering if there is a document/knowledge of unity’s ability to pass information from scene to scene. for example… a game consisting of 2 different areas, a map scene and a 3d scene, and you would like to pass the location of something on the map to the 3d scene…

Maybe this is Unity 101, I’m not sure.

Also, does anyone know of a broad poly limit for 3d scenes on the iphone 3gs/ipad? I have had alook around, but found no consensus.

Use static variables to pass data from scene to scene. And the poly limit on old devices should be somewhere under 8 thousand triangles. But on the newer devices probably a lot more, maybe 20 thousand triangles.
