No need for any lead into this post, just go to www.google.com on your iPhone and check it out. The interface has the “slick look and feel” like many other iPhone apps such as Facebook, and also incorporates heavy use of Ajax across all of the features.

For those without an iPhone, sorry, you won’t be able to see it, but here are some details. The menu across the top includes: Home, Gmail, Calendar, Reader and More. Clicking on “More” will provide you with links to Docs, GOOG-411, SMS, News, Photos, Blogger and Notebook.

In my limited use so far it seems like a very useful iPhone app for someone that uses Google extensively. If you use Gmail in the iPhone native mail app and use iCal/Outlook for your calendar needs then you might not get THAT much use out of it, but nevertheless it’s fun to play with and can be useful in certain situations like search and GOOG-411.
