HTML5 history in iOS safari 4.2.1 broken, Old webkit bug?

Merged with window.history.pushState not going back in history.

In regular safari my script changes the url of the page window.history.pushState and that works just fine but in ios, somehow the URL that gets loaded it that of the last page... It is really frustrating! is this a bug?

Thanks for your help :)

here is the code:

    function hijackLinks() {

        $('a').live("click", function (e) {
            e.preventDefault();
            loadPage(e.target.href);            
            $(this).addClass('click');

        });
        if((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i)) || (navigator.userAgent.match(/iPad/i))) {$('a').live("touchstart", function (e) {
             direction = $(this).attr('class');
            $(this).addClass('temp');
             setTimeout(function () {
                    $('.temp').addClass('click');
                }, 100);
        });
        $('a').live("touchmove", function (e) {
            $('.temp').removeClass('temp');
            setTimeout(function () {
                    $('.click').removeClass('click');
                }, 1);})

            $('.click').live("touchend", function (e) {开发者_如何学C

                else{

             $(this).addClass('click');})
              $('a').live("mouseleave", function (e) {

                sm = $(window).width();
                sn = $(window).scrollTop();

             window.scrollTo(0,0);

             window.history.pushState(null, null, url);

                if (direction === "leftnav") {
