A quick question for iOS 5 users... Under Settings>General>Usage you can very conveniently see all your apps and their size on the system and have a quick access to free up space... My question which nobody seems to have answered online is that obvioulsy apps like facebook, evernote and others that download data to work store or "cache" certain info...This in effect means that my Facebook App is approx 12MB but when i look at this including "Documents & Data" its over 430MB....tunein radio app had 262mb and its only an 11mb app. Now i can free this up by deleting the App and reinstalling but my question is, is there an easier way to do this? You can clear the cache in safari in its own personal settings but facebook or tunein radio doesnt have this....any ideas ??
