What happen when an app crash in Ios? viber was working fine, and suddenly crashed, and i can't open it again. I can't understand, how come deleting and installing the app can't fix the problem? It seems to me that my iPad don't uninstall it completely, and when i try to install it again, iPad remember that this app was crashed before, and again the app still keep crashing. If my idea is true, since my iPad is jailbroken, do we have any tweak or something to delete the app completely? Thank you in advance.
