Detect iOS version less than 5 with JavaScript

This is related to the fix for position:fixed in older versions of iOS. However, if iOS5 or greater is installed, the fix breaks the page.

I know how to detect iOS 5: navigator.userAgent.match(/OS 5_d like Mac OS X/i) but that won't work for iOS6 when it eventually comes around, or even iOS 5.0.1, only a 2 digit version.

So this is what I have atm.

$(document).bind(scroll, function() {

    if((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i)) || (navigator.userAgent.match(/iPad/i))) {

        if (navigator.userAgent.match(/OS 5_d like Mac OS X/i)) {

    }

    else {

        changeFooterPosition();

    }

});

This snippet of code can be used to determine any version of iOS 2.0 and later.

function iOSversion() {

  if (/iP(hone|od|ad)/.test(navigator.platform)) {

    // supports iOS 2.0 and later: <http://bit.ly/TJjs1V>

    var v = (navigator.appVersion).match(/OS (d+)_(d+)_?(d+)?/);

    return [parseInt(v[1], 10), parseInt(v[2], 10), parseInt(v[3] || 0, 10)];

  }

}



ver = iOSversion();



if (ver[0] >= 5) {

  alert('This is running iOS 5 or later.');

}
