The mobile Gmail application for Google Apps that used to only work if you had a Blackberry is now available for all mobile phones. Just go to m.google.com/a on your mobile phone and download "Mail by Google". The application looks exactly like the recently released Gmail Mobile 1.5, except that it has a blue icon and supports Google Apps accounts. You'll also notice that you can login with standard Gmail accounts.
It's unclear why Google didn't add support for Google Apps in the standard Gmail application (available at gmail.com/app), but it may have something to do with Google's branding and the Gmail name.Gmail, Mobile, Gmail Mobile Application, Google Apps, Google
