黑莓手机浏览器直接访问这个网页（web url）即可。

<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 7position = ua.indexOf("BlackBerry ") + 11;document.write("BlackBerry Model : " + ua.substring(position, position + 4) + "<br/>");            position = ua.indexOf("Version/") + 8;            document.write("BlackBerry OS Version : " +  ua.substring(position, position + 10) + "<br/>");position = ua.indexOf("Version/") + 8 + 6;bundle =  ua.substring(position, position + 3 );document.write("BlackBerry OS Version : " +  bundle + "<br/>");if (bundle < 649) document.write("WARNING: please contact IT to upgrade BlackBerry OS. Otherwise you may experience international roam problem when you go abroad.");else     document.write("Thank you, your device need no upgrade.");        }        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));document.write("You device is OS 4.2 - 5.0.
