IPhone – How to keep application data when synchronizing iPhone with new iTunes

applicationsdata synchronizationiphoneitunes

I want to enable app-synchronization between the iPhone and iTunes on a new computer.
I already transferred the apps from the iPhone to iTunes but when checking the box for synchronizing apps, iTunes still displays the warning message that the phone apps will be replaced by the iTunes apps.
The last time I did this, I still had all my apps but the in-app purchases got lost as well as any saved progress in my games.
This meant that I had to re-download the maps of my navigation app (skobbler). I'd like to avoid this as my monthly data volume is currently very limited.

Is there a way to synchronize without losing the application data?

To avoid this occasion, you have to save the app data manually. You can do it with any iOS file manager on PC (with i-FunBox for example).

There's one more way to backup the application data: the DataDeposit app from Cydia store uploads all the data of an application to Dropbox and is able to restore it automatically (jailbreak is required).
