How do I get the BlackBerry OS version via javascript or jquery in a Webworks app?
I tried the following code from a thread "detect blackberry os version" but it isn't working for me:
var limit = '4.5.0.127';
var version = /BlackBerry\w+\/([\d\.]+)/i.exec(navigator.userAgent);
if (version[1] && version[1] < limit) {
location.href='notcompatible.cfm';
}

<script type="text/javascript">
var ua = navigator.userAgent;
if (ua.indexOf("BlackBerry") >= 0) {
if (ua.indexOf("Version/") >= 0) { // ***User Agent in BlackBerry 6 and BlackBerry 7
Verposition = ua.indexOf("Version/") + 8;
TotLenght = ua.length;
document.write("Jorgesys BB OS Version :: " + ua.substring(Verposition, Verposition + 3));
}
else {// ***User Agent in BlackBerry Device Software 4.2 to 5.0
var SplitUA = ua.split("/");
document.write("Jorgesys BB OS Version :: " + SplitUA[1].substring(0, 3));
}
}
</script>
- be sure to have Javascript Enabled! =)

If you have experienced trouble detecting BlackBerry 10 (as I did after reading this answer!), be aware that the user agent string has changed in BB10, as explained in http://devblog.blackberry.com/2012/08/blackberry-10-user-agent-string/
In my specific case, I wanted to check if the version was just BB10, for which the next code is enough:
isBlackBerry: function() {
// Only works with the latest version: BlackBerry 10
return navigator.userAgent.match(/BB10/i);
}
