In my post jQuery Mobile - Programmatic Page Transitions Pt. 1 I answered a question in how one can programmatically navigate using jQuery mobile and select their page transitions. Now that jQuery Mobile 1.0a2 is out, some additional methods and utilities have been added.
You can find the additions here: jQuery Methods and Utilities
You no longer need to create a dom element and click it to cause a page navigation with a specified transition. The jQuery team has provided us with a new method to cause a page navigation.
