Thread:Extension talk:MobileFrontend/Auto detect on MW 1.18

Sorry for repeating this topic. I see that in the latest version a configuration option has been added for auto detection and redirection of mobile browsers to the mobile frontend. However, I'm using MW 1.18 and upgrading to MW 1.20 just for this is too much for me.

Will someone be willing to provide a simple step-by-step guide for redirection in MW 1.18? I'm using apache 2.2.22 on Ubuntu 12.04, PHP 5.3.10. I have root access, and can change whatever setting I need. I just need to know what to do. Thank you
