Google has updated the mobile version of their popular email application. Mobile Gmail is located at m.gmail.com.
The update now includes features from the full web mail client. Labels, spam and drafts.

There are also extra features now showing in the inbox. Archive, delete, report spam, add labels, mark as read and use of the stars.

You are also able to select either the enhanced AJAX version or the AJAX-Less versions. I have tried both and still prefer the AJAX-Less version on my smartphone.
