To prevent page from showing or redirect a user before next page is shown, you need to listen to pagebeforechange event. This event fires before changing page transition is commenced and URL History is updated.
When pagebeforechange is emitted, it omits a data object holding details of previous and next page. Use this data to determine from and which pages the user is navigating.
$(document).on("pagebeforechange", function (e, data) {
var nextPage = data.toPage,
prevPage = data.options.fromPage;
if (typeof nextPage === "object" && typeof prevPage === "undefined") {
var page = nextPage[0].id;
if (page === "pageone") {
$.mobile.changePage("#pagethree", {
transition: "flip"
});
return false;
}
}
});
Using .show() or .hide() will get you nowhere. In addition, refrain from using .ready() or $(function () {}); in jQuery Mobile and use Page Events instead.

Try to put your code inside pagecreate event:
Triggered when the page has been created in the DOM (via ajax or other) and after all widgets have had an opportunity to enhance the contained markup.
<script>
$(document).on('pagecreate', function() {
$("#pageone").hide();
$("#pagetwo").hide();
$("#pagethree").show();
});
</script>
