Official Google Mobile Blog: The Iterative Web App: A new look for Gmail and Google mobile web apps

We never want the buttons and toolbars of Google apps to compete with your content; rather, they should compliment them. So the headers and buttons are now darker, to better show the content of your emails and calendar entries.

We also made the all the buttons a bit larger, for easier button-tapping.

To try these apps yourself, point your mobile browser to Gmail (, Calendar (, Latitude (, Tasks (, or just go to from you phone and find all these web apps under the 'more' link.
