Personally, I use the mobile version of the site a lot, (I'm on iPhone) and whenever I click a link to go to... Say... A post, or the homepage or wherever else, every other link will bring me to the desktop version of the site. I don't know of a way to fix this (ametuer coder) but you could try defining the links better to differentiate the two.
While on the topic of the mobile version, it needs to integrate all the features of the desktop site, I've used many services that fail to do this, and it annoys me to no end... (Also, I've tried the IPboard app and it won't let me access this site..)
