Not sure where the question resides - it sounds like it worked. However, I haven't had much luck with the PhoneGap Desktop Application, especially after the last update where I can't even import my projects anymore.... Try this instead from the command line:
npm install phonegap -g //install phonegap-cli
phonegap create test //create starter project
cd test //go to test dir
phonegap serve //serve the application
Now on your phone's PhoneGap app, connect to the IP address listed after the server starts from 'phonegap serve'
I installed again and it works. Thank you
