The Google iPhone Interface was launched December 4, 2007 and includes several enhancements for browsing Google on an iPhone. In 2008, Google did a significant upgrade to make the google interface faster and include other applications like "iGoogle Gadgets". http://techcrunch.com/2008/01/14/google-beefs-up-iphone-interface/ In this way, third party developers can create "iGoogle" gadget third-party applications that can be used by iphone users immediately without having to wait for permission from Apple to feature and support their apps in "ITunes".

How to find and operate the Google iPhone interface
To get the new Google experience on the iPhone, open Safari browser which comes with all iPhones on the desktop, go to www.google.com and save the page as a bookmark or your homepage. On the main page, near the bottom, there should be a link listed iGoogle. Click on it and you will be taken to another page where you can choose to "sign in". Once logged in to your normal gmail account as you have on your normal computer, you will be able to choose the layout and preferences for your iPhone.

The first I-Phone Google interface of December 2007, included general search functions, direct Gmail access, a personal Calendar along with Google Reader. The next version which was launched a month later included the same functions, but the design was much sleeker, had a better UI (User Interface) and was a lot faster than the 2007 version. According to the official Google Press Center http://www.google.com/intl/en/press/annc/mobile_macworld_08.html, it makes it easier to switch between applications like the Calendar, Picasa photo collections, and Gmail. iGoogle gadgets like weather, stocks and news selections can be personalized to your iPhone desktop.
