If an app is running when the system begins installing an update, the system kills the running app before installing. The app will be launched the next time the user opens it.

When the system installs an app update, it deletes all files in the old version of the app bundle and then installs the files from the new version of the app bundle. If any files existed in the old app bundle but not in the new app bundle, they are gone after the app has been updated.

The user's files (such as the contents of the app's Documents directory) are not touched.

If your app hangs after you have updated it, then you have a bug that you should try to track down in the debugger.

UPDATE

If the user manually uninstalls the app, the system removes all of the user's documents for that app, and removes the user's preferences, and removes any other files (like cache files) associated with the app. So when the user uninstalls the old app before installing the new app, he is starting with a “clean slate”.

If the user just updates the app from the app store, without manually uninstalling the old version first, all of his existing documents and user preferences and cache files are still around. If the new version of the app doesn't understand one of those files or preferences, it might crash.

As the app developer, it is your responsibility to make sure the new version of your app is compatible with the old versions of documents, user preferences, caches, or anything else that might be around after an upgrade.

I don't have any idea how PhoneGaps works but as far as I know for iOS, the code is replaced by the new version when you download it from AppStore or somewhere else (MAM/MDM) but saved content (such as user preferences) is not removed.

First the user downloads the app from the store, then the code is replaced and finally iOS checks the validity of your certificates. If everything works well the new app is available.

There is no forced update, which means the user has to tap on the download button on the AppStore.
