I found several issue connected with CordovaSim FH & cordova.js >= 4.0.0:
1) Running against local FH cloud app fails with disabled proxy (need to use local by default) (UPD: reported as a separated issue - JBIDE-20590)
2) Running against remote FH cloud app does not work with cordovasim at all (for remote proxy the error is the following):

XMLHttpRequest cannot load https://rippleapi.herokuapp.com/xhr_proxy?tinyhippos_apikey=ABC&tinyhippos_…3A//aerogear-t-uy2f2glr7qrvs4k6rvfnj3ya-dev.ac.gen.ric.feedhenry.com/hello. Cannot use wildcard in Access-Control-Allow-Origin when credentials flag is true. 

Literally, this cordova hello world app does not work against FH app preview (It used to work before) (UPD: not a bug the app must be deployed firstly - JBIDE-20606)strong text
