Hum... Well jailbreak is a procedure which you use to free the iOS, once the iOS is free (jailbreaked) you will be able to do everything you want with the iOS, lucky for jailbreakers there is cydia store where you can find most of the apps/tweaks apple refuse to implement in the iOS.
So when I asked if you jailbreak or not, I wanted to know if your iOS was capable to handle apps/tweaks from
Cydia. Apparently you aren't jailbreak so I'm out of idea regarding your concern.
