So recently I jailbreaked my iPod touch with the spirit Jailbreak
and now for some reason whenever I install App Store apps they open and close instantly but my cracked apps work just fine I have tried restoring and doing various methods any help would be appreciated.
Ive had this problem - just go to the appstore and download a new app. It should ask you to sign in. When you sign in all the other apps should work. That is how i fixed it from personal experience. It seems the apps dont work if your not logged in to the store
