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 (gmail.com), Calendar (google.com/calendar), Latitude (google.com/latitude), Tasks (gmail.com/tasks), or just go to google.com from you phone and find all these web apps under the 'more' link.
