Lost app data
iPhone 4 using iOS 5 and iCloud backup
Have been running iOS 5 since with no problems. Tonight I connected the iPhone to a PC to sync/charge as per usual while I continued to do other tasks. After sync had completed in the background I happened to open an app on the iPhone to check some info only to find the app data gone!
Rather surprised at this I deleted the app from the phone and tried syncing with the PC again, ticking the app in iTunes so that it was re-installed. The app returned to the iPhone but again minus the data.
Finally I tried deleting the app again from the iPhone and re-installing from the pass purchases in the iPhone app store. Again the app re-installs, again no data!
As one might guess this data tied to the apps is important. Has anyone else had this problem and has a fix? What would cause this??
My one saviour might be a local PC backup I have of the iPhone from about a week or two ago on my work PC but I would rather not use that.

Still none the wiser about why this data got removed from my iCloud backup. A bit worrying and I think I will still be doing weekly local backups to my PC as well.
