I have updated jquery.mobile-1.0b2.js to jquery.mobile-1.2.0.js. I am getting jQuery undefined error. In the previous beta version, I have modified the js as

(function(jQuery) { // beta version code here.. })(custom.jquery); 

where custom.jquery is defined as

custom.jquery = jQuery.noConflict(true); 

in the jquery.js

I have done similar wrapping in the stable 1.2 js and got the undefined error. Without wrapping also got the same error. Please advice me
