Apple's new iCloud backup keeps your iPhone from getting clogged with files by moving them to the cloud. But now, files tucked away to stay local for offline use are getting "cleaned," meaning deleted.
Reported by the creator of Instapaper, an app to save information to read offline, this change in iOS behavior may delete files from ebooks, comic book apps, and non-iTunes podcasts gathered by apps. Since the offline use files have been hidden in areas not backed up (because their content changes so often), once they're "cleaned" they're gone.
