Xili-theme select is an automatic selector of theme according defined rules: one for current browsers and anothers for mobile browsers (iPhone, iPad)
$wp_ismobile->cookienable is set to 1, the theme can include a tag to refresh theme as viewing on a desktop browser even if on mobile. See tag example in php code.
shortcode is also available and can be inserted everywhere (the link built detects if current or not current theme active).
