Just recently, I've been getting this error from from iTunes when syncing my iPhone.
I generally have 300-400Mb free storage, but even if I only want to sync a 1Mb PDF in Books I'll get a similar message.
So, I delete an App of the appropriate size, do the sync and then redownload the App and I still have 300-400Mb of storage left.
This has only been happening for the past couple of months. Any ideas why this should be?
