Google Earth on the iPhone, But Why No Street Names?

Google Earth is now available on the iPhone, which is awesome.  Something about sitting in a coffee shop in the Washington, DC area and flying around Sydney, Australia on my phone is just very cool.  One frustration though.  No street names overlays.

I can understand that the iPhone version of Google Earth is necessarily more limited than the desktop version.  They provide the Wikipedia and Panoramio overlay layers.  Why not street names?  Google Maps for the iPhone certainly includes streets.  Hopefully this will come to Google Earth shortly.

Other than that, cool application.
