Using WPTouch 3.1.1? Are the search and menu buttons not working in the mobile view? Just add the following in the Branding | Theme Footer section under Theme Settings:
<script type="text/javascript">
jQuery('#search-toggle').off();
jQuery('#search-toggle').on('touchend', function (e) { jQuery('#search-dropper').toggleClass('toggled'); });
jQuery('#menu-toggle').off();
jQuery('#menu-toggle').on('touchend', function (e) { jQuery('#menu').webkitSlideToggle(); });
</script>
