I have create one iphone application(using phonegap) with .net webservice for back-end process and add this application on app store. After this I need to make some changes in both side. I need to wait minimum 7 days for getting approval this from app store. At this time an old iphone application should work successfully. for approval i will update the web service too. If i will update the web service, an old application won't work successfully. Before approve the app store team check this working.
Do you have any idea how to manage old version and new changes in web service.
