Yes you install cracked apps in your iPhone but AppStore is asking you to update them but you don't really want to . . . and if the AppStore badges annoy you, here is a way to remove them. Previously when Hackulo.us was still there, this function was included in Installous. Unfortunately, this is history. Also - there is an App called MetadataRemovr from repo.insanelyi.com but this is for older iOS releases (3.1 - 4.1) and i did not try this. First you need to find the Application code - for this I use SBsettings / App Folders
