All that I have is their HTTP_USER_AGENT string, unfortunately:
Mozilla/5.0 (Linux; U; Android 2.2; en-us; Nexus One Build/FRF91) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1
Is there any way in Zimbra for admins to add strings as mobile devices like was done for drupal in the earlier link to address the same problem? Or is this something that would need to be added by developers to the base code?
