Great development skills at MB-theme

Please I will like to suggest a plugin that can detect and auto redirect Opera mini browser
This is because i have a high level of traffic that comes from Opera mini users.
Opera mini works on my current theme (symnel) but i have just purchased Zara theme. so i need a way to redirect opera mini browsers to my mobile site that will work with my old theme.

NB: someone did something like this for IE-browser see link
