Hi, I have installed the Mobile Frontend extension in my pet project at http://espiral.org
I only get to the mobile view manually, through the link at the footer. Autodetection of mobile browsers doesn't seem to work or I have done / missed something in my installation. I have got feedback from a bunch of users with a bunch of devices, nobody got the mobile view by default and all of them get it when visiting http://en.wikipedia.org
Something that looks different in my installation compared to Wikipedia's is the lack of a redirect to a ".m." URL. I'm actually a bit confused about this. It is mentioned briefly at http://www.mediawiki.org/wiki/Extension:MobileFrontend but it is not clear to me whether this is something supposed to work automagically when installing the extension or whether there is something I need to do with the WURFL database, the LocalSettings.php, the web server...
Other than this the extension works great presenting the mobile view of pages. Thank you very much for your work!
