IPhone, iPad and other mobile browsers are stripped down and don't do rich text editing well (if at all).
This is an issue with all mobile browsers for all internet sites. It is not due to using the FASO software.
WYSIWYGs (What You See Is What You Get) are seriously lacking on Mobile Safari, across the board, due to a lack of features in the actual browser.
Mobile Safari's HTML 5 implementation doesn't support the content editable attribute, so the majority of the better WYSIWYG rich text editors (TinyMCE, FCKEditor, YUI's RTE) are disabled on the iPad and other iOS devices at this time.
