I am developing HTML5, CSS3 web site with jquerymobile. I want to display an error message like “Your mobile browser does not support this application” like message if the mobile device can’t render the page well or if it can’t apply jquery mobile styles. I couldn’t find a good article on this yet. So your help is highly appreciated.

As an example the application works fine on iphone but not in blackberry bold device. So I want to display such message for blackberry bold device users. I see that blackberry bold device doesn’t apply jquery styles to controllers.

Thank you

    JQM has a $.mobile.gradeA() function that returns boolean. Here is a list for JQM 1.1.0 of which browsers have “gradeA” support and return true. http://jquerymobile.com/blog/2012/04/13/announcing-jquery-mobile-1-1-0/#platforms

    if(!$.mobile.gradeA()​){
    alert('Your mobile browser does not support this application.');
}​​​​​​​​

    Update Please note that newer blackberry bold devices should return true for gradeA support. Anything blackberry 7 + is ok. Also note that a device can run jQuery just fine and still not style things appropriately. It is the css3 support that is lacking in most cases.
