While KendoUI Mobile has a nice and customizable iOS switch component, based on CSS and fonts, I want to suggest including to the framework also a language independent generic graphical switch component, where the ON state has an 'I' symbol and the OFF state has a 'O' symbol. This could be used as an alternative to the current CSS-version. Purely graphical version would ensure the native looks, which you can see in my forum post attachement here:
