I need a script added to my jquery/phonegap app to prevent users from uninstalling and then reinstalling the app. Actually it is OK if they reinstall but the app must recognize that it is the same phone that is reinstalling and must force the user to login with their original credentials. The app interacts with a database and user's registration info is stored there. More details will be provided. You need to show me that you have prior experience with phonegap and jquery.
If you cannot provide the script for Android 2.1 and can only provide it for 2.2 and beyond you need to tell me this in your bid.
