Currently Google Maps are working well on iPhone. Much better than Youtube. Om confirms this here.
I have been using Google Maps from day one on iPhone, but there are some missing things, which you would expect on a devoce that is launched in era of 2007. Apple should have implemented better usage of Bluetooth, and possibly given a feature to hook up a GPS device via Bluetooth to drive Google Maps. It is kinda painful to scroll, and zoom using multi-touch while driving, to find exactly where you are at the moment.
Hoping that improvements in bluetooth implementation brings in this functionality soon in iPhone.
