In updating my PhoneGap/Cordova app to the latest version, I came across the unpleasant surprise that the jQuery $.ajax function is no longer working.  I've made sure to whitelist domains properly and have done everything that I did when it was working, about a year and a half ago.  However, Cordova 2.6, jQuery Mobile 1.3, and jQuery 1.9 Ajax calls just don't work.  Especially on Windows Phone.  Maybe I'm just missing something, but breaking this functionality is frustrating.
