JQueryMobile MVC4 - Import iPhone and Android Contacts/Calendar

JQueryMobile MVC4 - Import iPhone and Android Contacts/Calendar

Hi All,
 
My architecture:
 
Backend:  NET 4.0, MVC4, C#
Frontend: jQueryMobile,  Javascript, HTML/HTML5, Razor Engine
 
Controller/Actions use .cshtml files to serve up Web Pages.
 
Is there a way that I can access iOS & Android Contacts and Calendar using some type of API callable from Javascript.
 
Thanks,
Joe
