leparlon, just follow the exact instructions from phonegap. Put any html files in the assets/www folder (as in the instructions) and Phonegap will automatically launch any index.html file automatically when you make the app. It's a lot of steps, but none of them are difficult. PM me or post a topic (or both) if you have problems.
I just made one and then rename it ("refactor" in eclipse terms). I keep using it and change any settings such as the app name and orientation.
It's also very well documented on how to hide the Android status bar for complete full screen, set which permissions you need and change the splash screen.
I haven't used Phonegap Build, how was your experience was that? Your app seems to run perfectly as far as I could tell.
I have a set of Phonegap games in the market that's just Javascript play.google.com/store/apps/developer
