I have a site using twitter bootstrap and am using some of the responsive features. It works fine on the desktop and the mobile devices. Shrinking my window on the desktop cause the responsive grid to kick in, and the responsive grid is served to the mobile device appropriately.
However, is it possible for an iPhone user to access the 'non-responsive' version? It's usually safe for iPhone and android phones to access the 'full' version of most sites, so I'd like to offer that as an option for the mobile users.
Back before 'responsive' was the hottest thing, this was typically handled via client browser detection and the backend routed the clients to two completely different sites, pages, or themes to render the content, and there was usually some kind of link or button afforded to the user to allow them to visit the full-site instead. I'm trying to replicate that usage pattern.
