There are a couple of supported gestures you should be aware of when using the PhoneGap Developer app.
3 Finger Tap
A 3-finger tap gesture will return you back to the home screen if you want to connect to a new IP address.
4 Finger Tap
A 4-finger tap gesture will cause the current application to refresh. The PhoneGap Developer app will automatically load any changes made but a forced refresh can be done with this gesture as needed.Edit this page on GitHub
