Google has done its bit in celebrating Macworld by upgrading the customised 'iGoogle' interface designed especially for the iPhone.  The first version, launched at the beginning of December, brought mobile Safari-friendly access of search, Gmail, Calendar and Reader to the handset, while this upgrade boosts speed, increases the flexibility in arranging tabs and options, adds automatic refresh to the Gmail inbox and brings iGoogle gadgets to the cellphone.

With plans to roll out the improved UI to international versions of the iPhone, as well as other handsets "that offer similar usability and browser capabilities", this will only add fuel to the rumors that Google see the iPhone as a test-bed for internet-based applications eventually to be found on their own Android cellphone platform.

You can access the new version by visiting www.google.com on your iPhone.
