I want to update an app but it asks for another Apple ID Yes, this is asked a lot, but most people suggest deleting the app and re-installing it with your own Apple ID. I can't do that, because I have made serious progress and I lose it all if I do that. You can't connect to the app through Game Center etc, so I can't transfer data that way either.

What can I do?
You have but two choices...


Use the Apple ID &amp; password that was originally used to download the app.
Delete the app &amp; re-download it under your own Apple ID.


There is no 3.
