I believe you are right.

The link posted in my pull request shows the source I used, which I found after Googling the user agent.
After your comment I found the official documentation at http://my.opera.com/community/openweb/idopera/ which clearly states that 'opera mobi' is to be identified as Opera Mobile. I'll commit an update.

Thank you for pointing it out.
