You need the iOS version of AF2 and go to the regions menu. It is not out for Android yet. You might get faster replies if you post in the mobile section "iPhone iPad" (it has not been renamed since the Android version came out).
Sorry, but we do not offer the Southern California region for Android yet. This has mainly technical reasons, as Android does not offer a direct download of In-App purchases, so we have to implement this ourself, which is fairly complicated to do right and reliable.
