How do I sync my apps without losing the app data?

I recently had to downgrade and then upgrade my iTunes version (don't ask) but was greeted with a blank screen in the Apps section of iTunes where my apps used to be. So I refilled all my old apps from the "mobile applications" folder on my PC. Now I have the same apps on both my iPhone 4 and in my iTunes library, just like they used to be.

However, when I try to click the 'sync apps' checkbox it says +"Are you sure you want to sync apps? All existing apps *and their data* will be replaced with apps from this iTunes library"+. I have a whole bunch of free apps with precious data attached to them that I would hate to lose. How can I sync iTunes and iPhone up again like they were in the good old days without losing all of this app data? It's driving me crazy.

Any help would be immensely appreciated.

Laptop, Windows 7

Hey all this is the closest thread I have found to the problem I appear to have. I have follow the steps outlined, transferred purchases and used 'backup' but when I look in the backup folder it is only 3gb, compared to the 29gb of data that I wish to fully backup. Using recording software and daws means that I really do need all of that data backed up, and I am most confused. The second directory mentioned contains what look like the install files for each app, again nowhere near the expected size if they contained my user data.

Honestly, I have to say I am a long way from an idiot, and even further from a Luddite, yet I find this to be incredibly obfuscated. It may be that I am o er complicating the issue, and I should just trust iTunes, but twenty years with computers has taught me better. Any advice, would be thoroughly appreciated.

You definitely don't have all your data backed up. The iTunes "Backup" isn't really a complete backup. It backs up system settings and some application data. To get the applications backed up you use "Transfer Purchases." But neither option will transfer media from the device to the computer. Sync-ing will just erase the media from the device. You must find a program or another means to transfer the data from the device to the computer. Some methods are free (more options for this if you can jailbreak), others will cost money. I haven't found a reasonably simple or complete method to get media content off an iPhone or iPad yet. If you find a good way to preserve all your precious information, please post back and let us all know.


Good luck!
