jQuery Mobile Persistent Footer in V.1.2.0

Persistent Footer.  Recent release 1.2.0 of JQM appears to fix the persistent footer problem in Internet Explorer 9.0.  Persistent footer does persist in DESKTOP IE9, but in Windows Phone 7.5 browser, the location is fixed to the bottom of the page.  In WP7.5 it does not persist to the bottom of the screen like it is supposed to do.  I does persist in Desktop Firefox, Desktop IE9, Safari Desktop and Safari IOS
