Is there any way to get any iOS app to clean up its cache etc? I heard there's a new 'cleaning' feature in iOS 5 where apps do that automatically. But I haven't seen any of my apps do that. I really need Facebook to clean itself up because it's taking up a lot of space. Is there any way to initiate an app clean up?
When I go to Settings > General > Usage, Facebook is listed as using 182 MB even though the app itself is only 10 MB.
