How to include newer version of jQuery in APEX 4.1?

Question

Hi,
I've included a newer version of jQuery and jQuery-UI in my page template according to APEX documentation (after #HEAD# in page template). However I am having some issues, for example the datepicker doesn't work anymore.
I've created an example here [url http://apex.oracle.com/pls/apex/f?p=47057:1]http://apex.oracle.com/pls/apex/f?p=47057:1. You can't select a date from the datepicker after it has been displayed on the screen.
Any help is greatly appreciated.
Regards,
Jure

Thank you all for help, from your posts I was able to get the datepicker working with a different version of jQuery (but not jQueryUI) included on the page. There are two methods:
1. Include the new library before #HEAD# and change the reference to a different variable, for example:
<script src="jquery-1.6.4.min.js" type="text/javascript"></script>
<script type="text/javascript">
  var jq164 = jQuery;
</script>
#HEAD#2. Include the new library after #HEAD# and enable noConflict() mode, for example:
#HEAD#
<script src="jquery-1.6.4.min.js" type="text/javascript"></script>
<script type="text/javascript">
  var jq164 = jQuery.noConflict(true);
</script>In both examples above, $, jQuery and apex.jQuery point to apex jQuery, while jq164 points to the new one.
However, I couldn't manage to include a newer version of jQueryUI. I only found a page ([url http://stackoverflow.com/questions/6358961/using-multiple-jquery-ui-versions]http://stackoverflow.com/questions/6358961/using-multiple-jquery-ui-versions) that says you have to specify a different context for each version of jQueryUI included on the same page. I haven't yet had time to look at this, so if anyone already knows how to do it, it would be really nice to share it with us.
