Google have added a kick-ass feature to Gmail. It already had a mobile version that you could access from any WAP browser, but it was cumbersome and slow. Now they’ve got a Gmail application that works with most modern phones. Point your phone at http://gmail.com/app to download it. It works a charm on my K750i, and is much faster and easier to use than the phone’s wap browser.

If you your phone gives error about having no suitable security certificate, follow the instructions given here.
