I've tried using mobile_theme to switch to a selected mobile theme when a mobile visitor browses. But using online mobile emulators: mobilephoneemulator.com and transmog.net I found that half of pages get shown as Desktop version pages.
I thought of using ThemeKey but I'll need to use browser version, operating system to serve mobile content. But it could fail for Googlebot, Bingbot etc, they also need to see my mobile pages.
Is there any alternative auto theme switcher for mobile? I'm on shared hosting and can't use Browscap etc php modules.
