Today, Google has released an iPhone application that puts Google’s numerous services into a single interface on a navigation toolbar. On further time, the application will also be available for other mobile devices. This application will give iPhone users the ability to switch between such Gmail, Calendar, Reader, and search by clicking on the navigation bar at the top.

This application is given away free by Google. With this decision, Google has more freedom in choosing which markets it wants to play in first; Google does not need to worry about market size and potential customer base.

A bigger market exists among Nokia mobile phone users running the Symbian OS and Nokia’s proprietary browser. However, according to Gummi Hafsteinsson, a product manager in the mobile group at Google, iPhone technology rather than market potential played a significant role in making the launch decision. Moreover, he said that the Safari browser on the iPhone is essentially the same as Mac OS X. Therefore, in many ways, the users will get the same capability as on the desktop.

According to the iPhone product manager, because Safari supports AJAX (Asynchronous JavaScript and HTML), which allows the system to fetch information in the background and enables the software to forecast where the user will go next, it can prefetch information for the next step, this can ensure the performance almost instantaneous when switching between applications.
