I have built my native app using command line. The mobile web version loads up in mobile safari and chrome with out issue. However when I package the app and load it on the iphone and android I just get a blank screen. I know the issue is probably something incorrectly coded, however how do I track this down. I want to tackle the iphone first.

I have xcode installed and can view the console for the phone but not seeing anything useful.only seeing <Warning>: 0.000000

any suggestions on programs and steps to tackle this?
