So I went to the menu where you can set cellular data use for apps. Under each app it has a size under the App name, so I am guessing that is the size of the App? I noticed on my phone the AppStore is listed as 959MB and Facebook is listed as 1.1GB. Is there a way to reduce the sizes of those two? I tried uninstalling FB and reinstalling it, but it went right back to that size. Any idea?
