I had a phone app that worked great using PhoneGap 1.0 on iOS4. Then after I upgraded XCode and PhoneGap to work with iOS5, my data service URL and Bing maps would no longer connect. It turned out that in PhoneGap.plist, I had to register any external links under external hosts. I also had to allow all whitelist URLs to show in the WebView control, which is under another property. Since I wanted to allow any external link to work, I simply added “*” to my external hosts.
