A couple of days back Google had launched the iGoogle for iPhone, see: Google: iGoogle For iPhone Launched!. Now on the first day of Macworld, Google's announced new enhancements to the integrated Google experience of Googling on the iPhone.

The earlier version was launched just over a month ago and featured a suite of web applications — including Search, Gmail, Calendar, Reader, etc — into a user friendly interface. The newer version is supposed to increase speeds and improve usability.

The New Features entail:

An Improved UI: The applications have gotten a face-lift and now look and feel more chic, in addition to their being easier to activate, navigate and be used via a touch-screen.

Customization of default tabs: There's now easier access to your favorite applications as you can customize the applications that show up on the Google.com menu bar. All you have to do is choose your favorite Google applications to bring them to the front menu, so they'll be just a click away whenever they're needed. Further you can even switch between applications with ease, as you only need to sign in once to access either of Gmail, Calendar, Reader, Docs or your Picasa account.

Faster Gmail: Two enhancements which ensure this are: First, the new emails will automatically appear so there's no need to manually refresh your inbox. Secondly, there's an auto-complete feature for contacts which would make composing emails a lot quicker.

Speedier Calendar: There's a new month view, which allows you to glance at an entire month of appointments.

iGoogle: You can now access your iGoogle gadgets on the iPhone. This includes each and everything you've customized on your iGoogle homepage including weather, stocks, and news feeds too would appear on your iPhones. You can customize your iGoogle page on your computer at www.igoogle.com.

Google even plans to expand these features to international versions of the iPhone and even to other platforms that offer similar usability and browser capabilities.
