From the PhoneGap FAQ:

Q. I want to create an application for phonegap to access externally deployed web services via AJAX. How can i resolve the issue with the cross-domain security policy of XmlHttpRequest?

A. The cross-domain security policy does not affect PhoneGap applications. Since the html files are called by webkit with the file:// protocol, the security policy does not apply. (in Android,you may grant android.permission.INTERNET to your app by edit the AndroidManifest.xml)
