Google has a special interface for mobile devices called Google Mobile (http://www.google.com/m) but when we talk about the iPhone or iPod Touch, Google has a separate interface for these Apple devices which makes use of the ajax technology in Safari.

Last month, Google introduced a special interface for iPhone and iPod Touch devices to help users get a more better Google experience and has since then streamlined the interface even further.

On the first day of MacWorld 2008, Google announced new improvements to the integrated Google experience on iPhone. These improvements have been made to Google applications such as Search, Gmail, Calendar, Reader, and more.

• Improved User Interface
• Customization of Default Tabs
• Speedier Gmail
• Speedier Calendar
• iGoogle for iPhone

For as far as I have experienced the new Google applications on my iPod Touch, I would say that I have seen good improvements in Google web applications e.g. Gmail and iGoogle. However rest of the applications and services need a lot of dressing up.

To test all these Google applications and services on your iPhone, just open Safari and visit the respective Google application or service.
