What KML fields are supported in the native Google Maps application on the iPhone?

Question

I have been doing some research on using maps in iPhone applications and it looks like most of my needs can be met passing KML data into the built-in google maps application, but I cannot seem to set the same values (phone, home page, address) that are available when performing a built-in search in the maps application. Does anyone know if there is any way to set those values, or what fields are available?

UPDATE: With the advent of the 3.0 OS and the Map API, applications no longer need to pass control to the built-in map application, so this question is no longer relevant.

Answer 1

KML is not officially supported by Apple as of now. It's specified in the URL schemes documentation. Any URL in the ?q= parameter will be ignored.

Answer 2

There are few options available for iPhone developers planning to use Google Maps in their software. I've seen sample code and implementations of WebKit that translates gestures to Google Maps loaded inside it, but performance is dismal at best. Doing a static map without a lot of zooming or scrolling is pretty much the only performance-preserving option until a native API is available.
